Report on Roadway Development Technology Audit – June 2010
EXECUTIVE SUMMARY
A self reporting Technology Audit was completed across underground mines, OEMs and suppliers, and mining contractors with a view to establishing the level of utilisation, effectiveness and need for further research associated with current roadway development related equipment and practices.
Respondents were also invited to identify key factors contributing towards the successful introduction and development of new technologies and processes, and those that were considered to be barriers to their successful introduction and development.
In overall terms, 63 individual technology elements covering the roadway development process were evaluated, including continuous miners, strata support, coal haulage, face ventilation, face services (eg; power, water in/out, compressed air, communications), materials handling, panel advance, and personnel transport. Respondents were also invited to comment against each element, particularly if technology elements had previously been trialled and/or installed but were currently not in use.
Responses were received from 19 longwall mines and 7 bord and pillar mines, 16 OEMs and suppliers, and 6 mining contractors.
Mines reported that 56% of the 63 technology elements were considered to be somewhat effective or extremely effective, with some 69% of those considered as somewhat or extremely effective also being used regularly or exclusively. Mines also reported that 73% of the technology elements were either likely to or extremely likely to benefit from further research. Results indicate that Mines tended to adopt a simple, low technology approach to roadway development, with “new”, higher technology elements (such as continuous haulage, auto‐cut facility for sumping and cutting, remote steering systems, machine auto‐reporting systems, self drilling bolts, push button controls on bolting rigs) not being widely utilised. Interestingly, a number of these low ranking “new” technology elements ranked high in regards to the Likely Benefit of Further.
Mines and Mining Contractors offered a wide range of comments in relation to earlier trials of the various technology elements, or potential benefits that could arise from further research. A number of observations were developed in respect to these comments, including:
The operational benefits offered by self drilling bolts are now being recognised, the challenge is to develop a range of competitive products, improve the understanding of potential cost/benefit relationships, and ensure potential operational gains from adoption of self drilling bolts are not lost in poor process management.
The potential benefits of remote (CM) steering systems are also being recognised, with further development and application of remote sensing technologies, video monitoring, and self steering systems considered as necessary to underpin the development of an integrated, high capacity roadway development system.
Push button controls on bolting rigs now offer improved consistency and quality of installation, the challenge is to take that control off the continuous miner and allow bolting rigs to be remotely operated/automated.
Bolting is recognised as perhaps the largest limiting factor on improving roadway development, with concurrent operation of roof and rib bolters seen as critical in respect to improving overall support cycles. Access to and escape from bolting platforms, coupled with the ergonomics associated with restricted space on the bolting platform appears to be limiting the adoption of concurrent bolting practices. The development of automated bolting and meshing systems coupled with development of remotely operated automated control system is likely to address such issues, as well as providing a more positive solution to the challenges posed by compliance with MDG35.
Report on Roadway Development Technology Audit – June 2010 Page 2
On‐board ducted ventilation systems or possibly the interface between the on‐board systems and roof mounted ducting system appears to be a significant constraint on overall ventilation effectiveness. The under‐platform ducting system developed for the Tahmoor MB610 warrants close evaluation, while adoption of continuous haulage systems (or monorails) might eliminate much of the manual handling concerns and reduce potential space constraints and/or conflicts.
The benefits afforded by adoption of machine auto‐reporting systems are again being recognised, however their broader adoption appears to be constrained by less than state of the art underground communication systems.
Machine diagnostic display units were seen as being invaluable, although there accuracy was questioned. Development of multiple access levels for operators and trades was identified as an opportunity, as was the development of a “black‐box” style data logging system to improve diagnostics, particularly in relation to unplanned movements of machinery.
Maintaining mine‐wide explosion suppression compliance was recognised as a significant challenge in 7 day operations, with the eventual approval of wet dusting systems being seen as a positive outcome.
In relation to the research, development and successful introduction of new technologies and processes Mines, OEMs and Suppliers reported a number of consistent themes, as summarised in Figure 1. As expected perhaps, Mines were critical of the level of support and commitment provided by OEMs in developing and introducing new technologies, whilst OEMs and Suppliers were critical of the lack of buy‐in by Mines to new technologies.

Report on Roadway Development Technology Audit – June 2010 Page 3
development and adoption of remotely operated or automated roadway development equipment as is contemplated by this report.
Unfortunately, the Audit does not identify the change management strategies adopted by mines when introducing new technologies and processes, nor does it reveal a sense of the level of success or otherwise achieved in regards to the introduction of new technologies and processes, ie; how often we succeed or fail, or how well we realise the full capability afforded by the new technology or process. The wide disparity in roadway development performance levels between best practice mines and the bulk of the industry suggests that much of the industry is failing to realise the full capability afforded by available or newly developed technologies, whilst a review of roadway development related technology developments over the past 20‐30 years might suggest that it is a long and difficult road from concept development to operational and commercial success.
Based on the Audit Findings and Conclusions it is recommended that ACARP’s Roadway Development Task Group maintains the general thrust of its CM2010 R&D strategy and where appropriate review R&D priorities in respect to the following key elements:
1. The development of technologies that enable bolting (and meshing) to be undertaken remotely, including: self drilling bolts (to minimise the number of process steps and components) bolt, washer, and mesh storage/handling systems and manipulating devices remotely controlled/automated bolting rigs and manipulators, and associated sensing and monitoring systems.
2. The development of technologies required to support a self steering remotely controlled continuous miner including: remote sensing seam profiling video monitoring machine navigation and steering communication protocols that facilitate integration of the differing technologies and
hardware (eg; miners, bolters, manipulators, haulage systems, etc), and machine supervisory/auto‐reporting systems (including the development of “black‐box”
data logging systems for machine diagnostics and failure analysis).
3. Addressing issues associated with on‐board ventilation systems, interconnections between on‐board and auxiliary ventilation ducting, roadway space constraints, and the overall effectiveness of face ventilation systems.
4. The development of shuttle car guidance systems (potentially as an off‐shoot to the development of continuous miner navigation systems) as a means of improving the consistency of operations and facilitating the development of a fully remote mining system.
5. Addressing issues associated with the management of face services, be it via the continuous haulage system or a monorail mounted face services system. In the latter instance methods need to be developed to enable the monorail to be extended remotely if a remotely operated roadway development system is to be employed effectively.
6. Development of strategies to address equipment certification and regulatory issues, including consideration of how the Earth Moving Equipment Safety Round Table (EMESRT) design guidelines may be applied in an underground mining context.
It was also recommended that mines continue to undertake ongoing operational research as a means to optimising face cycle times (ie; matching of cutting, haulage and support cycles), and to consider engagement of change management expertise as part of any strategy to introduce new roadway development technologies and processes.

INTRODUCTION
Representatives from underground coal mines, OEMs and suppliers, and mining contractors were invited to complete a self reporting Technology Audit which sought to identify the level of utilisation, effectiveness and need for further research associated with current roadway development related equipment and practices. Respondents were also invited to identify key factors contributing towards the successful introduction and development of new technologies and processes, and those factors that were considered to be barriers to their successful introduction and development.
An audit instrument was developed for mines (refer Appendix A) and circulated to mines by members of ACARP’s Roadway Development Task Group. Minor changes were subsequently made to that instrument to reflect the perspective of OEMs and Suppliers (refer Appendix B). Mining Contractors were subsequently supplied with both audit instruments and invited to complete that instrument which best suited their perspective.
In overall terms, there were some 63 individual elements covering the roadway development process, including continuous miners, strata support, coal haulage, face ventilation, face services (eg; power, water in/out, compressed air, communications), materials handling, panel advance, and personnel transport. Respondents were asked to identify in respect to each element whether:
individual equipment, technologies or systems were installed and/or available; their frequency of use; their relative effectiveness; and, their likelihood of benefiting from further research.
A four (4) point scale was provided to rank responses, with a ranking of 1 representing an extremely low level of utilisation, effectiveness, or likelihood of benefiting from further research, while a ranking of 4 represented an extremely high level of utilisation, effectiveness, or likelihood of benefiting from further research.
Respondents were also invited to comment against each element, particularly if technology elements had previously been trialled and/or installed but were currently not in use. Three further tables were included to enable respondents to identify key factors contributing to the successful introduction and development of new technologies and processes, barriers to the successful introduction and development of new technologies and processes, and major barriers to the successful research, development and introduction of new technologies.
The audit instrument utilised for OEMs and Suppliers asked respondents to identify:
whether the OEM/Supplier supplied the individual equipment, technologies or systems; to what extent where their products adopted; their relative effectiveness; and, their likelihood of benefiting from further research.
OEMS and Suppliers were similarly invited to comment regarding the application, trial and use of their equipment.
Responses were received from 19 longwall mines and 7 bord and pillar mines, 16 OEMs and suppliers, and 6 mining contractors. In only two instances were multiple responses received from a mine, OEM and supplier, or mining contractor, and in both instances were from a bord and pillar mine. A list of responding Mines, Mining Contractors, OEMS and Suppliers is provided in Appendix C.
All responses were processed utilising a JMP statistical package, with an average score being determined for each element based upon responses from individual groups or classes (ie; longwall mines, bord and pillar mines, OEMs and suppliers, mining contractors). Individual comments and observations were separately tabulated by question or element, again by individual groups or classes.

FINDINGS
Utilisation, Effectiveness, and Benefit of Further Research of Technology Elements
Key findings in relation to the Utilisation, Effectiveness and Likely Benefit of Further Research of the various technology elements as reported by Mines include:
Mines reported that 56% of the 63 technology elements were considered to be used regularly or almost exclusively (ie; an average score of 3.00 or more across all mine respondents).
Table 1 ranks Utilisation of the Technology Elements, with the 20 highest ranked elements highlighted in green and the 20 lowest ranked elements highlighted in pink. The levels of utilisation reported are perhaps consistent with the expectations of experienced roadway development operators, however a closer review of the 20 lowest elements suggests that the industry adopts a simple, low technology approach to roadway development, ie; elements not being widely utilised include continuous haulage, auto‐cut facility for sumping and cutting, remote steering systems (on continuous miners), machine auto‐reporting systems, self drilling bolts, push button controls on bolting rigs, powered cable and hose winders/storage, monorail mounted ducting, etc. Interestingly, a number of these low ranking “new” technology elements ranked high in regards to the Likely Benefit of Further Research as noted below.
Mines similarly reported that 56% of the 63 technology elements were considered to be somewhat effective or extremely effective (ie; an average score of 3.00 or more across all mine respondents) – with some 69% of those considered as somewhat or extremely effective also being used regularly or exclusively.
Table 2 ranks Effectiveness of the Technology Elements, with the 20 highest ranked elements highlighted in green and the 20 lowest ranked elements highlighted in pink. Again, the levels of effectiveness reported are probably consistent with expectations however, a closer review of the 20 lowest ranked elements identifies a number of manual operations or human factors as being somewhat less than effective, including; manual loading of bolting consumables, manual loading of mesh sheets onto the continuous miner, overall ergonomic configuration for CM operation, manual tendon/cable tensioning, maintenance accessibility and servicing, face services manually handled. Interestingly again, except for the ergonomic configuration for CM operations these manual operations or human factors did not rank high in regards to the Likely Benefit of Further Research.
From a statistical perspective there was a moderately strong correlation between low levels of utilisation and low levels of effectiveness (coefficient of correlation 0.7), suggesting that less effective elements were less likely to be utilised. This was partially supported by the relationship between higher levels of utilisation and higher levels of effectiveness (coefficient of correlation 0.4). What is somewhat surprising is that some “new” technology elements such as remote steering systems on continuous miners and continuous haulage systems, which have low levels of uptake (utilisation) across the industry, were reported as having low levels of effectiveness.
Mines reported that 73% of the 63 technology elements were either likely to or extremely likely to benefit from further research (ie; and average score of 3.00 or more across all mine respondents).
Table 3 ranks Likely Benefit from Further Research of the Technology Elements, with the 20 highest ranked elements highlighted in green and the 20 lowest ranked elements highlighted in pink. Those elements reported as being more likely to benefit from further research include a number of “new” technology elements such as; self drilling bolts, remote steering
Report on Roadway Development Technology Audit – June 2010 Page 6
systems (on continuous miners), continuous haulage mounted services, wet dusting, and machine diagnostic systems.
Those elements considered less likely to benefit from further research largely include proven technology elements (eg; bolt washer dispensers, east/west chain and rotating arm/spinner loading configurations, breaker feeders, area lighting, cable and hose boats), with few “new” technology elements.
When viewing the combined results of Tables 1, 2, and 3, (ie; Utilisation, Effectiveness, and Likely Benefit of Further Research) it was evident that technology elements that were considered to be more effective tended not to be ranked as benefitting from further research, although conversely, those considered to be less effective were not necessarily considered as likely to benefit from further research. There was a stronger correlation however between lower levels of utilisation and likely benefit of further research than there was between the level of effectiveness and likely benefit of further research.
It was not possible to similarly rank responses from OEMs and Suppliers as in most cases respondents only serviced a limited range of process elements and technologies, ie; the number of OEM and Supplier responses was statistically low. Table 4 details OEM and Supplier rankings by process element and technology (and also includes comments made by OEMs and Suppliers in relation to the application, trial and use of their equipment or services).
Respondents Comments
Mine and Mining Contractor respondents offered a wide range of comments in relation to earlier trials of the various technology elements, or potential benefits that could arise from further research and development. Table 5 tabulates these responses based upon the Likely Benefit of Further Research ranking, and includes comments from longwall mines, bord and pillar mines, and OEMs and Suppliers. A number of observations are offered in respect to these comments, including:
The operational benefits offered by adoption of self drilling bolts are now being recognised, the challenge is to develop a range of competitive products, improve the understanding of potential cost/benefit relationships, and ensure potential operational gains from adoption of self drilling bolts are not lost in poor process management.
The potential benefits of remote (CM) steering systems are being recognised, with further development and application of remote sensing technologies, video monitoring, and self steering systems being necessary to underpin the development of an integrated, high capacity roadway development system.
While push button controls on bolting rigs now offer improved consistency and quality of installation, the challenge is to take that control off the continuous miner and allow bolting rigs to be remotely operated/automated.
Bolting is recognised as perhaps the largest limiting factor on improving roadway development, with concurrent operation of roof and rib bolters seen as critical in respect to improving overall support cycles. Access to and escape from bolting platforms, coupled with the ergonomics associated with restricted space on the bolting platform appears to be limiting the adoption of concurrent bolting practices. The development of automated bolting and meshing systems coupled with development of remotely operated automated control system is likely to address such issues.
While improved ergonomics on‐board continuous miners was noted, there was considered to be major opportunities to further improve ergonomics, particularly associated with bolting, handling of mesh, access platforms, and cables and hosing.
While the objectives of MDG35 appear to be well understood and accepted, it appears that there is still substantive work to be done to develop and implement appropriate technologies
Report on Roadway Development Technology Audit – June 2010 Page 7
that provide productive solutions, including removal of operators from the contact zone through automation of bolting.
On‐board ducted ventilation systems or possibly the interface between the on‐board systems and roof mounted ducting system appears to be a significant issue in terms of both a constraint on overall ventilation effectiveness, the interface between the systems and access under or around ducting, and the adoption of larger capacity shuttle cars to balance cutting and support cycles. The under‐platform ducting system developed for the Tahmoor MB610 warrants close evaluation, while adoption of continuous haulage systems (or monorails) might eliminate much of the manual handling concerns and reduce potential space constraints and/or conflicts.
While one longwall mine considered it all too hard, a bord and pillar mine which operated a continuous haulage system reported significant advantages from installing face services on the continuous haulage.
Machine diagnostic display units were seen as being invaluable, although there accuracy was questioned. Development of multiple access levels for operators and trades coupled with improved training were seen as opportunities to improve existing systems. The development of a “black‐box” style data logging system was also seen as an opportunity to improve diagnostics, particularly in relation to unplanned movements of machinery.
The benefits afforded by adoption of machine auto‐reporting systems are again being recognised, however their broader adoption appears to be constrained by less than state of the art underground communication systems.
Maintaining mine‐wide explosion suppression compliance was recognised as a significant challenge in 7 day operations, with the eventual approval of wet dusting systems being seen as a positive outcome.
A number of mines reported concerns with the overall effectiveness of face/mine ventilation systems, particularly in respect to respirable dust levels, quantity and capacity (distance), and noise levels.
The installation of 6m long victaulic pipes coupled with the size and manoeuvrability of existing pipe installation equipment is an issue at a number of mines, and is expected to warrant further research and development to establish systems and equipment to support higher capacity development systems.
Introduction of New Technologies and Processes
Respondents were requested to identify and rank up to five (5) new technologies and processes they consider had been successfully introduced, and to identify the key factors they considered had been instrumental in the successful introduction of those technologies and processes (respondents are asked to rank these key factors from 1 to 4, with a ranking of “1” indicating the most positive factor of those identified). Table 6 shows the consolidated responses from mines, with responses from longwall mines being identified with a highlighted ranking. Figure 1 over summarises these key factors.
While respondents did not consistently complete the table in the manner proposed, Table 6 highlights a number of reoccurring themes in respect to the successful introduction of new technologies and processes, including; product or project champions, robust change management processes, involvement of personnel, company support and involvement, good planning, demonstrated productivity and safety benefits, reduced manual handling, introductory training.
These themes are also reflected in Tables 7 and 8 which detail the responses of Mining Contractors and OEMs/Suppliers in relation to the successful introduction of new technologies and processes.
Report on Roadway Development Technology Audit – June 2010 Page 8
Respondents were similarly requested to identify and rank barriers or factors that have impacted the introduction of up to five (5) new technologies and processes that they have been associated with, and to identify root causes of these barriers or impacts wherever possible. Table 9 shows the consolidated responses from mines, with responses from longwall mines again being identified with a highlighted ranking. Again, Figure 1 summarises these key factors.
Again a number of reoccurring themes were evident in mine responses, including; cost, certification and regulatory issues, lack of OEM support and commitment, lack of operator buy‐in, lack of corporate commitment and management support
OEMs and Suppliers (Table 11) also identified certification and regulatory issues, a lack of operator buy‐in and resistance to change as barriers to the successful introduction of new technologies.
Respondents were similarly requested to identify and rank major barriers to the successful research and development of new technologies. Table 12 shows the consolidated responses from mines, with responses from longwall mines again being identified with a highlighted ranking. Again, Figure 1 summarises these key factors.
Themes evident in the mine responses included; funding, costs, OEM commitment, cost, research being too “pure”, lack of corporate support for R&D, over‐commitment of R&D funding to longwall operations (the profit maker), or lack of or inability to apply technological solutions to roadway development challenges.
OEMs and Suppliers (Table 14) again identified funding and development costs, certification and regulatory issues, low cost sourcing by mines, end user acceptance, and a lack of project champions as key barriers to successful research and development of new technologies.

roadway development challenges
Figure 1: Summary of Key Success Factors and Barriers to New Technology and Processes
While Mines, OEMs and Suppliers reported a number of consistent themes, as summarised in Figure 1, Mine respondents were also critical of the level of support and commitment provided by OEMs in developing and introducing new technologies, as were OEMs and Suppliers critical of the lack of buy‐in by Mines to new technologies. This dichotomy is perhaps fuelled by the Mines’ preference to develop localised solutions to their technology requirements (with perhaps a leaning towards higher level technologies), whereas OEMs seek to develop global products in order to offset development costs (with perhaps a leaning towards lower or simpler levels of technology).
Equipment certification and regulatory issues have also been identified as a major barrier in the introduction of new technology and processes (and is possibly a factor in OEMs’ preferences towards lower technology solutions) and is expected to be a major consideration in the development and adoption of remotely operated or automated roadway development equipment.
Unfortunately, the Audit does not identify the change management strategies adopted by mines when introducing new technologies and processes, nor does it reveal a sense of the level of success or otherwise achieved in regards to the introduction of new technologies and processes, ie; how often we succeed or fail, or how well we realise the full capability afforded by the new technology or process. The wide disparity in roadway development performance levels between best practice mines and the bulk of the industry suggests that the industry is failing to realise the full capability afforded by available or newly developed technologies, whilst a review of roadway development related technology developments over the past 20‐30 years (eg; Maintel Development Machine, Kemcoal Beaver, Joy 1FCT – 4FCT, Klockner Becorit continuous haulage, Joy Sumps Shearer, Mobile Boot Ends, 12CM20, 12CM30, ABM20, ABM25,) might suggest that it is a long and difficult road from concept development to commercial success.
Again unfortunately, the Audit does not identify the change management strategies adopted by mines when introducing new technologies and processes. a sense of the level of success or otherwise achieved in regards to the introduction of new technologies and processes, ie; how often we succeed
CONCLUSIONS
The Technology Audit provides an industry wide picture of the level of utilisation and relative effectiveness of current roadway development equipment and systems. The Audit also identifies potential areas for further research and development together with the challenges associated with the research, development and introduction of new technology and processes into an underground environment.
The Audit clearly identifies that in overall terms bolting is perhaps the most significant challenge facing the industry in respect to improving roadway development performance, including:
self drilling bolts push button controls on bolting rigs concurrent operation of roof and rib bolting rigs improving ergonomics associated with access to and operation of bolting rigs addressing issues associated with the adoption of and compliance with current Guidelines
(MDG35).
Whilst ever continuous miners are required to operate within a 5.0–5.4m wide 2.5–3.5m high operating envelope, provide effective roof and rib support within metres of the face, be able to break away and mine cut throughs between adjoining roadways, and cut coal at instantaneous rates of 30‐40tpm, it is unlikely that designers and manufacturers will be able to incorporate the concurrent operation of manually operated bolting and meshing systems within an ergonomically acceptable on‐board work environment.
Report on Roadway Development Technology Audit – June 2010 Page 10
Therefore, future roadway development R&D should, as a priority, focus on developing technologies that enable bolting (and meshing) to be undertaken remotely, including:
self drilling bolts (to minimise the number of process steps and components) bolt, washer, and mesh storage/handling systems and manipulating devices remotely controlled/automated bolting rigs and manipulators, and associated sensing and monitoring systems.
A continuing focus on the development of technologies required to support a self steering remotely controlled continuous miner should also be maintained, including remote sensing, seam profiling, video monitoring and navigation technologies. These technologies need to be supported by state of the art underground communication systems, the development of communication protocols that facilitate integration of the differing technologies and hardware (eg; miners, bolters, manipulators, haulage systems, etc), and the development of machine supervisory/auto‐reporting systems (including the development of “black‐box” data logging systems for machine diagnostics and failure analysis).
Current research into automated bolting and mesh handling systems has identified significant issues in regards to space constraints in and around the continuous miner, particularly in respect to potential conflicts between bolt and mesh storage/handling systems, and on‐board ducting systems and connections to the auxiliary ventilation ducting. Similar constraints were identified by mines in the Audit in respect to on‐board ducting systems and connections to the auxiliary ventilation ducts, and between roof/monorail mounted ducting and shuttle cars, with mines also identifying issues in respect to the effectiveness and capacity of current face ventilation systems.
The development of higher capacity roadway development systems will result in higher linear rates of advance in gateroads, which in turn is likely to result in increased rib emissions (unless more extensive gas drainage is undertaken). Further consideration of issues associated with on‐board ventilation systems, interconnections between on‐board and auxiliary ventilation ducting, roadway space constraints, and the overall effectiveness of face ventilation systems is warranted as an emerging priority.
Batch haulage systems (eg; shuttle cars, battery/diesel haulers) are unlikely to surface as a major constraint to improved roadway development performance until such time as self drilling bolts and automated bolting and meshing systems are developed and adopted, and utilised in conjunction with concurrent sumping, cutting, and bolting operations. Further, the matching of cutting, haulage and support cycles has recently been recognised as a major contributor to improved development rates, with a number of mines increasing the size of shuttle cars to optimise current face cycles. Larger shuttle cars have also introduced issues in respect to space constraints in roadways, particularly in regards to shuttle car/ventilation duct interferences and the application of monorail mounted services management systems. Ongoing operational research by mines into the optimisation of face cycles is warranted (ie; matching of cutting, haulage and support cycles), while the development of shuttle car guidance systems, potentially as an off‐shoot to the development of continuous miner navigation systems, may offer improved consistency of operation and facilitate the development of a fully remote mining system.
The introduction of continuous haulage systems into bord and pillar operations will provide an opportunity for longwall mines to evaluate the potential application of proven continuous haulage systems to gateroad development, not only as a coal clearance system but as a means of mounting face services on the haulage system to eliminate manual handling of ducting, cables, and hoses. Monorails are increasingly being utilised to manage face services and are reportedly highly effective however full integration of the ventilation system has largely been ignored, with the weight of monorail segments understood to be a limiting factor. The development of a remotely operated mining system will require means to manage face services, be it via the continuous haulage system or a monorail mounted face services system. In the latter instance methods need to be developed to enable the monorail to be extended remotely.
Report on Roadway Development Technology Audit – June 2010 Page 11
The concept of developing a high capacity roadway development system capable of sustained production rates of 10MPOH 20 hours a day as contemplated by ACARP’s CM2010 R&D strategy is expected to reflect similar key success factors, and to experience similar barriers to its successful development as experienced with existing technologies. While the project objectives may appear visionary, there is an emerging recognition that adoption of emerging technologies such as bolter‐miners, self drilling bolts, and continuous haulage systems could, in best practice mines, almost realise the 10MPOH objective – the challenge then is to make that rate sustainable, and to minimise or eliminate process downtime. The project also has other key factors in its favour, being the recent highly successful development of the longwall automation system under the ACARP banner, with a number of the key longwall automation players also being involved in the Roadway Development Task Group. The Task Group also recognises the necessity of developing a critical mass to pursue development and adoption of the necessary technologies, and to gain OEM commitment and support for their commercialisation. The successes achieved by Earth Moving Equipment Safety Round Table (EMESRT) in developing design guidelines for surface mining equipment are also likely to be applicable in an underground mining context, and may become an essential element in any strategy aimed at addressing current certification and regulatory issues.
RECOMMENDATIONS
It is recommended that ACARP’s Roadway Development Task Group maintains the general thrust of its CM2010 R&D strategy and where appropriate review R&D priorities in respect to the following key elements:
1. The development of technologies that enable bolting (and meshing) to be undertaken remotely, including: self drilling bolts (to minimise the number of process steps and components) bolt, washer, and mesh storage/handling systems and manipulating devices remotely controlled/automated bolting rigs and manipulators, and associated sensing and monitoring systems.
2. The development of technologies required to support a self steering remotely controlled continuous miner including: remote sensing seam profiling video monitoring machine navigation and steering communication protocols that facilitate integration of the differing technologies and
hardware (eg; miners, bolters, manipulators, haulage systems, etc), and machine supervisory/auto‐reporting systems (including the development of “black‐box”
data logging systems for machine diagnostics and failure analysis).
3. Addressing issues associated with on‐board ventilation systems, interconnections between on‐board and auxiliary ventilation ducting, roadway space constraints, and the overall effectiveness of face ventilation systems.
4. The development of shuttle car guidance systems (potentially as an off‐shoot to the development of continuous miner navigation systems) as a means of improving the consistency of operations and facilitating the development of a fully remote mining system.
5. Addressing issues associated with the management of face services, be it via the continuous haulage system or a monorail mounted face services system. In the latter instance methods need to be developed to enable the monorail to be extended remotely if a remotely operated roadway development system is to be employed effectively.
6. Development of strategies to address equipment certification and regulatory issues, including consideration of how the Earth Moving Equipment Safety Round Table (EMESRT) design guidelines may be applied in an underground mining context.
Report on Roadway Development Technology Audit – June 2010 Page 12
It is also recommended that mines continue to undertake ongoing operational research as a means to optimising face cycle times (ie; matching of cutting, haulage and support cycles), and to consider engagement of change management expertise as part of any strategy to introduce new roadway development technologies and processes.

3.45 2.01 Concurrent operation of roof and rib bolters
Longwall Access to roof rigs is an issue when rib bolting, therefore operators tend to support roof then rib with 2nd operator assisting to
install top rib bolt. Have to switch from roof to rib bolters Concerns regarding the ability of the inbye operator to escape the face in the case of fall or outburst are an issue with concurrent
bolting. To leave the bolting on automatic has issues with the rigs jamming up and spitting steels out Standing in front of rib borer in bad ground (ribs) ‐ no protection for operator using roof bolting rigs Requires greater ergonomic consideration. Current configurations provide very small working envelope Emergency escape issues Use of new technology is proposed (eg; SDB) ‐ new miners being built can use all 6 rigs together Bord & Pillar Bolting is still one of our biggest delays to production, takes 1 min to cut a metre and 3 minutes to bolt it ( on minimal support
level, next level up is 6 minutes) Two bord & pillar mines and one longwall mine reported that rib bolts were not utilised, and therefore not an issue

dust control as being an issue with concurrent operations One mine noted that the current system would support while another noted that the current miners being employed did not allow
for cutting & bolting simultaneously Bord & Pillar A mine utilising a continuous haulage system reported that it was still restricted by bolting cycle times, hence coal clearance was
not an issue 3.28 3.06 Pedestrian interaction measures

1 Self drilling rock bolts Bolting rig OEM's need to take on the project of rig designs to pump resin inside a hollow bolt
Onesteel (our only Australian rebar manufacturer) needs to invest in pierced billet hollow bar technology. Importing such high volumes of steel from china etc and holding 3 months stock is just not practical.
The purchasing/ contracts departments of large mining companies are attacking suppliers. The poor margins and low returns limit the potential for private investment into such an important technology
Current funding into this technology has been into professional researchers. That lives on funding rather than live on profits from inventions because they don't come up with practical solutions!
1 Pipe Monorail systems ‐ with flexible vent ducting and/or cables mounted thereon (whether or not other components are mounted)

APPENDIX A: ACARP ROADWAY DEVELOPMENT TECHNOLOGY SELF AUDIT – MINES Introduction The following audit has been prepared by the Roadway Development Task Group to evaluate the effectives of existing roadway development technologies and processes and to identify and prioritise areas for further research. Respondents are asked to complete the self audit and return it to Gary Gibson ([email protected]) by 25 February 2010 for reporting at the upcoming Roadway Development Workshop (16, 23 and 24 March 2010). Please note that the audit is designed to be completed electronically and respondents will be required to save their completed audit before returning the completed form by email. Individual audit responses are confidential to ACARP and any details published will be on a consolidated industry basis without detailing individual mine responses or respondent’s details.
Instructions for Completing Audit Respondents are asked to respond to four basic questions across the roadway development process, namely:
1. Is the identified technology or process employed or installed at the mine? 2. In the event that such technology or process is employed, how often is that technology utilised in day to day operations? 3. In the event that such technology or process is utilised in day to day operations, how effective is that technology or process in achieving the desired process outcomes? 4. To what extent could the technology or process benefit from further research?
To respond to the first question respondents are asked to insert either a Y or N in the grey response cell to indicate whether the technology or practice is employed or installed at the mine or not. If the answer is in the affirmative (Y), respondents should then tab to the next column and respond to the second question by inserting a number from 1 to 4, the number representing the heading descriptor which most closely corresponds to their view as to how frequently the technology element is utilised at their mine – ie; number 1 corresponds with extremely rarely whilst at the other extreme number 4 represents used almost exclusively. Respondents can then tab to the next column to similarly respond regarding the effectiveness of that technology or process, and to the fourth question to identify the extent to which such technology or process could benefit from further research (NB: if a negative response (N) is given to the first question respondents should proceed immediately to the next Technology Element or row and continue the audit as above). Respondents should then tab to the Comments column to make any relevant comments in respect to the use, effectiveness and research potential of the identified technologies and processes, eg; “... technology X previously employed and found to be ineffective due to ..............”, or “... further research warranted on technology Y to overcome issues associated with ...........” and “... poor operator acceptance of technology Z due to ............”. Provision has also been included to allow respondents to include other Technology Elements as appropriate by typing in a technology descriptor within the grey descriptor cell, and completing their assessment of that technology as above. Respondents are also invited to complete three other questions relating to the introduction of new technologies and process, namely:
Key Factors Contributing to the Successful Introduction of New Technologies and Processes – respondents are requested to identify and rank up to five (5) new technologies and processes they consider have been successfully introduced, and to identify the key factors they consider have been instrumental in the successful introduction of those technologies and processes.
Barriers to the Introduction of New Technologies and Processes – respondents are similarly requested to identify and rank barriers that have impacted the successful introduction of up to five (5) new technologies and processes.
Barriers to the Successful Research, Development and Introduction of New Technologies – respondents are asked to prioritise the top five (5) “technologies for further research” as reported in their Audit, and to identify what they consider may be major barriers in their successful research, development and introduction.
Respondents are also requested to complete the Respondent’s Details at the completion of the Audit to facilitate follow up if required. Again, it is noted that individual responses will remain confidential to ACARP.

APPENDIX B: ACARP ROADWAY DEVELOPMENT OEM/SUPPLIER TECHNOLOGY SELF AUDIT – OEMs AND SUPPLIERS
Introduction The Roadway Development Task Group proposes to evaluate the effectives of existing roadway development technologies and processes and to identify and prioritise areas for further research. Separate self audits have been prepared for both mines and OEM/suppliers with OEM/supplier respondents being asked to complete the self audit and return it to Gary Gibson ([email protected]) by 24 February 2010 for reporting at the upcoming Roadway Development Workshop (16, 23 and 24 March 2010).
Please note that the audit is designed to be completed electronically and respondents will be required to save their completed audit before returning the completed form by email. Individual audit responses are confidential to ACARP and any details published will be on a consolidated industry basis without detailing individual responses or respondent’s details.
Instructions for Completing the Audit Respondents are asked to respond to four basic questions across the roadway development sector, namely:
5. Has the OEM/supplier supplied or installed the identified technology at Australian underground coal mines? 6. In the event that such technology has been supplied, how broadly has that technology been adopted at mines? 7. In the event that such technology has been supplied and is utilised in day to day operations, how effective is that technology being employed by mines – ie; are mines fully utilising
the installed capacity/capability of the technology, and/or are they realising the full potential of the technology? 8. To what extent could the technology benefit from further research?
To respond to the first question respondents are asked to insert either a Y or N in the grey response cell to indicate whether the OEM/supplier supplies the technology to the industry or not. If the answer is in the affirmative (Y), respondents should then tab to the next column and respond to the second question by inserting a number from 1 to 4, the number representing the heading descriptor which most closely corresponds to their view as to how broadly that technology is adopted at mines – ie; number 1 corresponds with extremely rarely whilst at the other extreme number 4 represents used almost exclusively. Respondents can then tab to the next column to similarly respond regarding how effectively that technology is being employed, and to the fourth question to identify the extent to which such technology could benefit from further research (NB: if a negative response (N) is given to the first question respondents should proceed immediately to the next Technology Element or row and continue the audit as above).
Respondents should then tab to the Comments column to make any relevant comments in respect to the development, introduction, and adoption, of the identified technologies, and the need for further research, eg; “... introduction and uptake of technology X was impacted by ..............”, or “... further research warranted on technology Y to overcome issues associated with ...........” and “... poor operator acceptance of technology Z due to ............”.
Provision has also been included to allow respondents to include other Technology Elements as appropriate by typing in a technology descriptor within the grey descriptor cell, and completing their assessment of that technology as above.
Respondents are also invited to complete three other questions relating to the introduction of new technologies, namely: Key Factors Contributing to the Successful Introduction of New Technologies – respondents are requested to identify and rank up to five (5) examples of where new technologies
have been successfully introduced at mines, and to identify the key factors they consider were instrumental in the successful introduction of those technologies. Barriers to the Introduction of New Technologies – respondents are similarly requested to identify and rank barriers that have impacted the successful introduction of new
technologies at mines in up to five (5) instances or examples. Barriers to the Successful Research, Development and Introduction of New Technologies – respondents are asked to prioritise the top five (5) “technologies for further research” as
reported in their Audit, and to identify what they consider may be major barriers in their successful research, development and introduction.
Report on Roadway Development Technology Audit – June 2010 Page 66
Respondents are also requested to complete the Respondent’s Details at the completion of the Audit to facilitate follow up if required. Again, it is noted that individual responses will remain confidential to ACARP.
