PROPOSAL FOR WORK AUTHORITY - WA1287 - NOTICE OF STATUTORY ENDORSEMENT

I refer to the work plan variation application (PLN-001343) for new works at the Georges Creek quarry in northern Victoria received on 2 August 2019.

The work plan variation application was found to be satisfactory and was statutorily endorsed on 20 February 2020 under section 77TD(1) of the Mineral Resources (Sustainable Development) Act 1990 (MRSDA).

A list of the referral authorities who have been given a copy of the work plan variation application in accordance with section 77TE of the MRSDA is attached. You should now apply for planning permission. You should note that you are required to submit the following documents to Council as part of the application for the planning permission:

• A copy of this Notice • Statutory Endorsement Information for Council • A copy of the attached Statutory Endorsement Referral Authority Checklist

• Copy of Referral Authority responses (if no response included then none was received)

• An unaltered stamped version of the work plan that was statutorily endorsed • A copy of the attached work plan specific conditions (if any) - which include conditions

that have been requested by referral authorities under section 77TD{3) of the MRSDA.

Following the issue of the planning permit you need to lodge the endorsed work plan variation together with the planning permit to Earth Resources Regulation. The endorsed work plan variation will then be approved.

After the work plan variation is approved, you will be advised of the remaining requirements for the grant of the Work Authority (Extractive Industry) .

I enclose a check list for the approval of a work plan. Please return the checklist with all the required items attached.

Please note that it is an offence to operate without required approvals.

WA 1287 Work Plan Variation for Blasting

PLN-001343

This Work Plan Variation (WPV) has been prepared for Tallangatta Construction and Maintenance (TCM) for their Georges Creek Quarry WA1287.

This WPV is only to authorise the ongoing use of blasting and associated operations (drilling) and does not change the processing operations, development sequencing, the rehabilitation plan or the community engagement plan approved in the November 2010 Work Plan.

This WPV will accompany a submission to Towong Shire Council to obtain an amendment to Planning Permit 2006/032, as required by Towong Shire Council via email date 18 June 2019, a copy of their advice is attached as an adhoc document TowongShireCouncil_AdvicePP2006-032.pdf

Background: The Georges Creek Quarry is a phyllite (or more accurately is a shale and spotted phyllite variety interbedded with slate, of Upper Ordivician origin) that has traditionally been won with a dozer in a rip and push operation . As the site has developed into fresher material the rock has become harder, and as a trial, TCM approached Earth Resources Regulation in 2017 to obtain approval to conduct some trial blasts. To date three trial blasts have been conducted with excellent results, with TCM now looking to gain ongoing approval for blasting, as identified in the latest ERR approval for blasting letter dated 25 Feb 2019.

Description of the Work Plan Variation PLN-001343. This WPV is to include blasting as an option to liberate the insitu rock. It is emphasised that blasting will supplement and not replace the rip and push operation. The rip and push operation is more suited to the upper, weaker materials. It is also emphasised that nothing else in the approved Nov 2010 Work Plan is changing.

As required by ERR in their "Trial Blasting" approval letters, and as part of TCM's community engagement plan, TCM consulted with the Towong Shire and neighbours prior to undertaking each of the three trial blasts. Feedback from the community has been very favourable, with only positive comments and no complaints.

Assessment of Risks: The risks directly associated with blasting have been considered in the Risk Treatment Plan - Blasting, attached as a risk treatment plan in RRAM. In addressing the risks associated with blasting consideration was given to the frequency of blasting (perhaps in the range of 4-6 a year) and the noise and dust generated from the drilling of the blast holes. A separate Risk Treatment Plan was not developed for drilling as it is considered the controls described in the 2010 Work Plan for the rip and push operation adequately address the risks of noise and/ or dust from the drilling operation. This has been verified by the community feedback/comments that they (the local land owners) prefer the drill and blast operation over the rip and push operation.

The location of the local residences is presented in Figure 1 below (a google earth screen capture), with the landowner, Graeme Hillias being the house immediately north (approx. 700m from the WA boundary) of the quarry, with other residences (sensitive receptors) being at least 800m from the WA boundary. This screen capture shows there are no new residences (sensitive receptors) since the 2010 Work Plan.

Monitoring results from two of the three trial blasts were made available to the ERR Bena Ila Compliance team. A copy of these blast monitoring results is included as an ad hoc document WA1287_ Tria/8/astResults.pdf for review by other ERR personal if required. The location of the 2017 monitoring location is identified in the attached documentation (to the east, on Georges Creek Road), and whilst it is acknowledged that the location of the 2019 blast is missing, it is anecdotally advised as the same as the 2017 location.

These roads are not trafficable, are not open to the general public and are not considered as receptors for the sake of blasting. As described in the Blast Management Plan, the Blast Exclusion Zone restricts access to the site, and by default, restricts access to these unmade roads.

Given there is only 1 risk described by this WPV, a Risk Register has not been completed. This WPV includes a Risk Treatment Plan for blasting, as well as the Blast Management Plan, which given the closest receptor is in excess of 700m, is considered satisfactory.

A copy of the TCM Blast Management Plan is also included as an ad hoc document WA1287GeorgesCreek_BMP_R2.pdf.

There will only be a small number of blasts each year, somewhere in the vicinity of 4-6. Blasting times will be restricted to 10:00am to 4:00pm. Every blast will recorded on video, with the video file available for review via the appropriate log in details. Given the infrequency of blasting, TCM commit to monitoring the first 3 blasts for overpressure and ground vibration, and then at least one blast per year thereafter unless directed otherwise by ERR. If there is any exceedance in blasting results, the monitoring frequency will reset, ie monitor the next 3 blasts. Blast monitoring results will be available to the Quarry Manager and filed on site for review by the ERR Compliance team.

All blasting activities are conducted by appropriately trained, qualified and licenced shot firers and explosive supplier contractors. The Quarry Manager, Richard Sharpe, has held a shot firer's licence (Lie No. 001400013102) since 2013, and as well as being responsible for the three shots at WA1287, the Georges Creek Quarry, has also been responsible for blasting at WA894, TCM's Sandy Creek Quarry and for Vic Roads. Additionally the shot design and layout is a collaborative process involving the Shot Firer, the Quarry Manager, the blast hole drilling contractor and explosive supplier to ensure shot design and layout is planned and managed safely and efficiently, with minimal risk. All explosives required for the blast, along with the relevant primers, detonators, delays and any other associated supplies are delivered to the site on the day of the blast on an as needed basis from an accredited external supplier. The quantity of bulk explosive required for each shot is predetermined and only the required explosives (and a small contingency) are delivered on the day of the blast. Any excess explosives, primers, detonators, delays are removed from site by the blasting contractor on the day of the blast. There is no storage of explosives, detonators or any explosive materials on the Work Authority.

Risk Treatment Plan - Blasting

Scope This risk treatment plan is for the control of blasting nuisance at sensitive receptors beyond the boundary of the Work Authority.

Key sensitive receptors

The key sensitive receptors associated with this hazard include:

There are no receptors with in 500m of the WA boundary.

Since the early 2000's the site has been operating as a mechanical (rip and push) extraction operation, with the last Work Plan Variation approved in November 2010. As the site has developed into fresher, harder material, TCM approached ERR for permission to conduct some trial blasts and since July 2017 has conducted three blasts with the approval of ERR. The closest receptor, Graeme Hillias, the landowner is 700m north of the WA boundary, and in excess of 750m from the blasting sites. The closest sensitive receptor is approximately 850m north east of the WA boundary, and in excess of 900m m from blast sites. Whilst "on paper" a road reserve exists on the northern and eastern boundary of the Work Authority, there is no evidence on the ground of this and it has not been considered as a receptor.

Blasting is a highly regulated activity with very prescriptive legislation and regulation . A Blasting Management Plan is developed and implemented for each blast as per regulations. No road closures or public traffic management systems have been required given distance to closest receptor (greater than 500m). No complaints and only favourable comments have been received from the local residences.· Blasting would be infrequent, approximately 4-6 times per year. All blasting associated activities are undertaken by appropriately trained and where required , licenced individuals or contractors. There will be no storage of explosives, primers, detonators, delays or other such explosive materials on site . All material required for the blast will be delivered on the day of the blast, with all excess material removed the same day.

Objectives

The key objectives of this risk treatment plan are to:

• Minimise potential for excessive ground vibration and overpressure to sensitive receptors (nearby residences).

• Minimise potential of fly rock.

Compliance standards

The compliance standards for this risk treatment plan are:

• Ground vibration (peak particle velocity) below 5 mm/s in at least 95 per cent of cases in a 12-month period and must not exceed 10 mm/s at any time as measured at sensitive receptors unless other limits or standards are applied by ERR, the Council or other regulatory agency.

• Air blast below 115 dB(L) in at least 95 per cent of cases in a 12-month period and must not exceed 120 dB(L) at any time at the closest receptor.

• Fly Rock No fly rock to leave the blasting exclusion zone. • Blasting management plan/s in accordance with the Section 130 of the Dangerous Goods

(Explosives) Regulations 2011 and Appendix 2 of AS 2187.2-2006 Explosives - Storage and Use - Use of Explosives.

Acceptance criteria

The acceptance criteria for this risk treatment plan are:

• No fly rock leaving exclusion zone • No blasting related issues/complaints experienced by nearby sensitive receptors

Introduction

1. Overview

This Blast Management Plan together with Shot Firers Report aims to meet the requirements set out in section 130 of the Dangerous Goods (Explosives) Regulations 2011 and appendix 2 of AS 2187-2-2006 Explosives Use

and Storage Part 2: Use of explosives.

The Blast Management Plan (BMP) takes the form of a risk control plan and is used in explosive blasting at the Georges Creek Quarry. The BMP is prepared by the Shot Firer before every blast and after consulting with all those involved in the blast.

2. Purpose of Blast Management Plan

The purpose of the blast management plan is to ensure blasts do not harm people in the area and to limit damage

to the environment.

This is achieved by:

On Site

• Ensuring a safe site is provided for blasting operations

• Ensuring a safe exclusion zone is maintained

• Detailing the objectives for the blast

• Identifying risks and hazards associated with the objectives, including control and/or mitigation measures

• Identifying site-specific requirements including selection of personnel, training programs and communication systems

• Adopting the BMP as part of the overall blasting process, ensuring all tasks conducted in a planned manner

• Controlling the blast process from design to initiation, evaluation and misfire treatment.

• Implementing a review process to assess completion of objectives.

Off Site

• Implementing blasting management measures (monitoring) to ensure compliance with regulatory requirements and Work Authority conditions

• Assuring compliance with approval/contract specifications.

• Assuring the safety of the public, site personnel and surrounding properties

• Ensuring no damage to people, property, machines, livestock, infrastructure or environment

• Responding to any complaints in timely and professional manner

• Ensuring the impacts of blasting operations on the surrounding community are minimised

Where required, the plan shall be submitted to a regulatory authority for authorisation.

Consideration is given to the possible environmental impact of air blast overpressure and ground vibration when design the shot.

6. Blasting Necessity, Frequency and Timing

Blasting has been identified as one of the key activities at hard rock quarry sites. Blasting is an essential part of the quarrying process and must be undertaken in a way that does not endanger people or cause damage to property, equipment or environment. The blasting procedure is required to fragment the raw rock source material to a size that can be loaded and hauled into the crushing plant for processing.

The nature of blasting creates noise, vibration and dust. There may also be a risk of fly rock that could result from loading procedures, blast design or rock conditions.

Background: The Georges Creek Quarry is a phyllite ( or more accurately is a shale and spotted phyllite variety interbedded with slate, of Upper Ordivician origin) that has traditionally been won with a dozer in a rip and push operation. As the site has developed into fresher material the rock has become harder, and as a trial, TCM approached Earth Resources Regulation in 2017 to obtain approval to conduct some trial blasts. Prior to this BMP, the site has conducted three trial blasts with excellent results, motivating TCM to gain ongoing approval for blasting. It is emphasised that blasting will supplement and not replace the rip and push operation. The rip and push operation is more suited to the upper, weaker mate1:1,als.

Blast design is a collaborative process involving the shotfirer, Quarry Manager, drilling contractor and explosive supplier. This ensures site specific factors and site experience are married to wider industry experience to maximise shot efficiency and safety.

It is anticipated that the site will require 4-6 blasts a year.

Blasting times will be restricted to 1 0:00am to 4:00pm, Monday to Friday

Blasting may take place at any location within the approved extraction area. The approximate location of each blast is recorded on the Shot Firers Report.

7. Blasting Arrangements

On initial entry to site all third parties must adhere to company policy and minimum regulatory requirements.

All third party contractors working on the site are inducted before being allowed to work.

TCM use contractors for the drilling and supply of explosives ( detonators, primers, bulk explosive, delays initiators etc) Shot layouts and blasting design are prepared by TCM personal in consultation with drilling contractors and explosive suppliers.

rs. Consultation and Communication

Extemal Consultation System

The Quarry Manager is responsible for notifying all potentially affected property owners / occupiers within 1 000m of the site at least 24hrs before and on the day of the blast. Currently there are 4 properties that are notified, see Figure 2 above.

Notification prior to the day of the blast is by way of direct contact, a phone call or a text message, indicating the proposed date and time of the blast. Notification on the day of the blast is by way of direct contact, a phone

[ call or a text message, indicating the time of the blast.

Quarry Site Manager (QSM)

Contact Name Phone Number

The Quarry Site Manager is responsible for site operations including authorization of the Shot Firer to commence with blasting operations. The Shot Firer is responsible for all aspects of the blast.

As the QSM gives final authorisation to fire the shot, they must be responsible for guaranteeing that the site is prepared for blasting.

Responsibilities specific to blasting are:

• Shot layout and design (spacing, burden, number of holes, angle of holes, hole depth) • Ordering explosives • Ensuring adequately trained personal available on the day of the shot • Ensuring all people on the shot are adequately trained in their tasks. • Ensuring standard exclusion zone protocols are appropriate for the shot • Final authorisation to fire the shot.



Shot Firer

The Shot Firer is responsible for use of explosives during blasting operations as well as the concept of designing, loading and firing. The Shot Firer is responsible for the shot in the event of a misfire. The name of the person will be nominated for each blast in the Shot Firers Book [CMPA 1340]

The Shot Firer is the final authority on who can access a shot, what can and cannot be done on a shot and what items can and cannot be brought onto a shot.

Responsibilities specific to the shot are

• Displaying "DANGER BLASTING IN PROGRESS" signs at appropriate locations • Conducting pre shot inspection of blast area • Establishment of the Blast Exclusion Zone • Ensure removal of all Mobile Plant & Personnel from Blast Exclusion Zone. • Direct supervision of the priming and loading of all blast holes • Direct supervision of the tie in and stemming of each blast hole • Direct supervision of any surface delay layouts • Enforcement of Blast Exclusion Zone, including final run through the area • Direct supervision of Blasting Siren protocols • Firing the shot • Inspection of shot and post blast • Sounding ALL CLEAR siren • Completion of all paperwork / reporting requirements

Shot Firer's Assistant I Trainee Shot Firer

The Shot Firers Assistant or Trainee Shot Firer(s) are to assist the Shot Firer as directed. Their details will be entered for each blast in the Shot Firers Book [CMPA 1340]

Responsibilities are:

• ONLY follow direct instructions of Shot Firer.

10. Training

For the purposes of this section, "working on a shot" is considered to include all tasks involved in the preparation of a blast, including (but not limited to) accepting deliveries of and transport of explosives, stemming, charging, firing and inspecting.

TCM have a zero tolerance policy on drug and alcohol. ALL PEOPLE on the site must be fit for work and free from of any drug or alcohol.



12. Risk Treatment Assessment.

A detailed risk assessment and associated Risk Treatment Plan is included in the WA1289 Work Plan documentation . A copy of the Risk Treatment Plan aw at October 2019 is attached.

In summary the closest sensitive receptor is in excess of 700m.

Work Authority Considerations

Since the early 2000's the site has been operating as a mechanical (rip and push) extraction operation, with the last Work Plan Variation approved in November 2010. As the site has developed into fresher, harder material, TCM approached ERR for permission to conduct some trial blasts and since July 2017 has conducted three blasts with the approval of ERR. The closest receptor, Graeme Hillias, the land-owner is 700m north of the WA boundary, and in excess of 750m from the blasting sites. The closest sensitive receptor is approximately 850m north east of the WA boundary, and in excess of 900m m from blast sites. Whilst "on paper'' a road reserve exists on the northern and eastern boundary of the Work Authority, there is no evidence on the ground of this and it has not been considered as a receptor.

Blasting is a highly regulated activity with very prescriptive legislation and regulation. A Blasting Management Plan is developed and implemented for each blast as per regulations . No road closures or public traffic management systems have been required given distance to closest receptor (greater than 500m). No complaints and only favourable comments have been received from the local residences. Blasting would be infrequent, approximately 4-6 times per year. All blasting associated activities are undertaken by appropriately trained and where required , licenced individuals or contractors. There will be no storage of explosives, primers, detonators, delays or other such explosive materials on site. All material required for the blast will be delivered on the day of the blast, with all excess material removed the same day.

13. Security

Site Security

W~1287 Georges Creek Quarry

The site is fully fenced with minimal gated access points.

Sentries are placed at all access points and are in direct communication with the shotfirer.

Magazine Security There are no explosives stored on the site. There are no Magazines on the site.

14. Capital Plant and Equipment

All vehicles, tools or other equipment used in the preparation and/or firing of the shot must be safe and maintained to company standards. The use of old or defective equipment on a shot is extremely dangerous and will result in disciplinary action.

15. Traffic Management & Signage

On the morning before a blast, signage is placed at the approach to the WA boundary (see the red line in the figure below, at the Exclusion Zone Boundary), as well as the WA entrance and all other entry points to the blast area. Signage is in accordance with explosives regulations. This signage is to notify people of blasting operations on site as well as notifying upon entering a blast exclusion zone.

The site office is the control point for all persons entering the site where they will be notified of blast operations and restricted access areas. Any unauthorised entry to the blast exclusion zone will be monitored by the Shot Firer or responsible person with unauthorised persons to be removed from the area and reported to Quarry Site Manager.

On site vehicles moving explosives around site are to be signed and have appropriate placard indicating type of explosives being carried. All signage and & vehicle requirements must comply to explosives transport regulations

16. Blast Exclusion Zone

Given the small size and the general layout of the operation a "universal" Blast Exclusion Zone has been developed that essentially closes the quarry to all people not involved directly with the shot. This includes all employees, sales trucks, visitors, contractors etc not directly involved in the shot.

The Blast Exclusion Zone is presented on the image below, which bars access to the quarry approximately 170m north of the WA boundary to all but essential personal on the day of the blast, and takes into consideration the generally accepted industry norms of 150m behind the shot and 400m in front of the shot.

The size of the exclusion zone is such that all fly rock and associated debris is contained within the zone, as well as consideration of blast environmental limits on humans and, where required, animals.



The exclusion zone may be comprised of an inner zone to restrict unauthorised entry to the shot which will be identified by being cordoned off with flags , signs, hazard blast cones or other suitable means and the full extent, which will be enforced prior to firing the shot. Guards or sentries will be positioned to maintain a blast exclusion zone immediately prior to and during the firing process.

The Shot Firer may remain in the exclusion zone, at a predetermined protected location during firing. All other persons on site will be directed to a nominated site blast shelter before the firing sequence can commence.

Management of the exclusion zones will be coordinated by the Shot Firer and Quarry Site Manager within requirements of AS2187.2-2006 Appendix L Exclusion Zones.

17. Surroundings and Environment

Blast designs will be planned to minimising risk to infrastructure, flora and fauna by adhering to ERR blasting guidelines (listed above in Section 12 Monitoring), and adjusting charge mass as appropriate.

18. Environmental Conditions

Weather

Weather forecasts are check by the Quarry Manager several days out prior to ordering the explosives and again on the day before the shot.

In the case of unexpected poor weather on the day of a blast, all persons must comply with the risk assessment and safe work procedures as directed by the shot firer.

Where explosives are involved, all emergency procedures should follow Section 5 of AS 2187 .1 - 1998.

As per Dangerous Goods (Explosives) Regulations 2011, if an electrical storm, thunderstorm or dust storm approaches a site where blasting operations are being conducted-

( a) all persons must withdraw to a safe distance from any explosive, including those explosives contained m a magazine, blast hole or in the course of transport on the blasting site and must not return until the storm has passed; and

(b) the Shot Firer or, in the Shot Firer's absence, a person authorised by the Shot Firer must keep the blasting site under observation from a safe distance.

Fire

In case of a wildfire, all persons are to follow the site ' s Wildfire Plan.

Due to the considerable risk to fire-fighters, fires in general proximity to loaded shots, external magazines or

within magazines should not be fought, all personnel should be removed to a safe location and access to the magazine secured.

If a fire threatens a loaded shot, the QSM will declare an emergency situation and all personnel will be evacuated

to a safe location outside the exclusion zone.

If a bushfire threatens an area containing an external magazine then, if safe to do so, -

• Any explosives or detonators outside shall be promptly placed inside the magazine or, if safe, removed

from site.

• The magazine should be closed and locked;

• Every person shall be withdrawn to a designated safe area prior to the arrival of the bushfire;

• The person in charge of the magazine shall be available to advise and assist local firefighting authorities;

and

• No person shall return to the external magazine until a competent person determines that it is safe to do

so.

Operating Parameters

19. Record of Blast

The Shot Firers Report must be completed and approved by the Quarry Site Manager and Shot Firer for every

shot. This document will cover all shot specific requirements of the shot which are not covered within this BMP. This includes specifying:

20. Management of Explosives

Approved explosives products

• WetHoles:

• Dry Holes:

Ordering Explosives

The Quarry Manager is responsible for organising the delivery of bulk explosives and all other consumables

required for the blast.

Accepting Explosives onto Site



The Shot Firer is responsible for inspecting the explosives and other consumables to ensure they are sufficient and appropriate for the blast.

Storing and Handling Explosives

It is this site's policy that explosives will only be delivered to site as required on the day of blasting.

Theft of Explosives

Any evidence of attempted forced entry to or theft of explosives from a supply truck or unaccountable stock discrepancy shall be immediately reported to the police. In addition such thefts shall be reported to WorkSafe Victoria on 13 23 60.

21. Blast Hole Management

Surveying/ Profiling: The Quarry manager and shotfirer shall inspect the blast face and check the front row for correct burden and toe and make any notes re stemming on the blast design report.

Drilling: The drillers log is consulted and all blast holes are checked for depth and any obstructions prior to loading, with any comments /. Instruction noted on the blast design report. driller

Approval for loading. Approval for loading will be given by the Quarry manager after consultation with the driller and shot firer.

22. Blast Parameters

Spacing, Burden, Face Height

The typical design spacing of shot holes on this site, when using full strength bulk explosive in an 89mm diameter drill hole is nominated in the table below:

Note; This table will not apply if a different strength explosive or a different diameter drill hole is used.

Face Height Minimum Minimum Front row Maximum toe Sub Drill

Burden Spacing Burden burden Depth

10m 3m 3.5 m Min 3 3.5 0.9

Any deviation in excess of 15% from the above values will be reviewed and signed off by an appropriately qualified and experienced blasting consultant before firing the shot.

Stemming

On this site, a minimum of2.5 meters of stemming must be used in all blasting operations. If special activities require the blasting of a face so small that it will not allow the minimum stemming, the design of the shot must be sent to an appropriately qualified and experienced blasting consultant for approval.

Blast Charging Procedure

Requirement Example £:" .. ;-l-

Define the blast area Ensure a 1 Om clearance beyond any blast holes

requiring charging. Blast barricading Signs and barricades are appropriately placed at all

access ways to the blast site. Visually inspect the blast face Ensure that the blast face is consistent with any blast

data that has been provided. Check access/ egress Ensure all vehicle access / ramps are safe for use.

Shotfirers planning meeting All personnel assisting on the blast must be made

aware of how to do each task safely. Laying out stemming Ensure appropriate stemming material(7-14 mm clean

aggregate) is placed at locations around the blast to suit manua or mechanical handling.

Label all blast holes Blastholes must be labelled according to the loading

chart. Blasthole check Provide evidence of actual blasthole depths i.e.: Drillers

Logs, dipping charts. Check actual burden against design using fishing pole method and/or Laser Profiling and Bore tracking methods.

Identify all exception holes Ensure all blastholes that require special loading

techniques are clearly identified for all personnel

assisting on the blast. Dip blastholes and record actual drill Compare the actual depth of all blastholes against the depths design depth. Backfill if necessary and record any short depth

blastholes. Lay out the boosters and downlines Work systematically to ensure that no blastholes are

missed. Carefully place the booster and downline or leadwire a

the blasthole collar to avoid any boosters, downlines or lead wire~

disappearing beneath drillings or down to the blastholes.

Assemble pnmers and lower intc Carefully insert the detonator into the booster according blastholes to the procedure and lower the primer into the blasthole.

Determine the appropriate explosives Use ANFO or a dry bulk explosive in dry blastholes

only. Use packaged or a water resistant bulk explosive in wet

and drv blastholes. Secure the downline while loading the Anchor the downline or leadwires with a rock or place blast hole. your foot over it to · prevent losing the downline or

leadwires into the blasthole.



15. Ensure that the explosive column is rising If cavities or voids are present the explosive column

may slump which may then require air decking or the

I placement of a solid deck. 16. Check the explosive column Use a measuring tape or a non ferrous measuring pole

to check that the collar heights do not exceed their design.

17. Secure the downline while stemming the Slowly tip the stemming material into the blastholes and blast hole make sure not to disturb or destroy the blasthole collar,

stemming must be sufficient to prevent flyrock.

18 . Check the initiation timing plan Check the initiation timing plan to ensure it is a true representation of the actual blast pattern.

19. Connect initiating explosive system Connect the downlines or leadwires according to the

design. 20. Check the tieup Walk the shot and check that all blastholes are

connected properly to the surface initiating system. 21. Securing the blast area Determine all access ways into the blasting area and

ensure the site procedures are adequate. 22. Blast guards Determine the positions of blast guards or road blocks.

23. Communication Ensure that any blast guards have a method of

communication and understand the firing siren sequence and their meaning.

24. Firing position The firing position must be at a safe distance from the blast site to be out of range of any flvrock.

C

C

C

L C

Once the Shot Firer has tested the circuit (if electric), the following warning sequence will occur:

Series of 3 audible si nals followed b a ause not less than 3 minutes

2 audible signals

1 minute pause followed by a continuous audible signal for 10 seconds

Blast fired as soon as possible after the continuous audible signal has ceased

Shot firer inspects site to ensure safe to carry on

All clear sounded for 10 seconds

Confirming all clear following the firing of the blast:

Stay within shot firer shelter until safe to move out

i Wait for regulatory times ( no personnel in area for 5 minutes if initiation method was electric

or signal tube, 30 minutes if safety fuse was used)

i Shot firer to wait for dispersal of all fumes and toxic gases, approach shot and view for any

signs of misfire

+ Once satisfied area is safe, shot firer gives all clear for work to normalise

+ Continuous audible siren for 10 seconds

25. Blasting Method

Blasting methods are fine tuned over time from each the site. Face heights, face orientation, sub drill, hole diameter, hole angle, blasting patterns, explosive types, loading techniques, stemming height, initiation type and firing sequences have been determined to meet blast design parameters governed by the sites acceptable environmental limits, source rock geology, type and size of loading tool and fragmentation required to meet crushing plant size and feed rate needs.



Blasting may be conducted using non-electric initiation or electric initiation with non-electric the preferred method. Where possible the overall size of the blast should take into account cost savings provided by suppliers for using full truckloads of bulk explosive.

All the above mentioned aspects of blast design may be reviewed over time as new products and technology becomes available, or if source rock geology or environmental limits change.

26. Monitoring Protocols

Air Blast Overpressure & Ground Vibration

Given the infrequency of blasting, it is expected that at least the first three blasts will be monitored for air blast overpressure and ground vibration, then at least once a year.

If any blasts exceed the allowable limits then the monitoring frequency will reset.

Allowable levels (AS 2187.2- 2006 Australian Standard Explosives- Storage and handling Part 2: Use of

Explosives) are as follows

Issue Level Allowable exceedance

Air blast overpressure 115 dB (Lin Peak) 5% of the total number of blast over a 12 month period

120 db (Lin Peak) Nil

Ground vibration 5 mm/s 5% of the total number of blast over a 12 month period

10 mm/s Nil

Fly Rock

All blasts will be videoed to keep a record of the blast and to assist in analysis/investigation of any fly rock events. Any unusual level of fly rock (rock ejected outside of the inner exclusion zone) generated by blasting, with the potential to cause a safety risk will be noted for each blast. This information will be used to continually

re-assess the adequacy of blast design controls in reducing the generation of fly rock. This information will also be used to re-assess the size of the blast exclusion zone.

28. Assessment prior to a post-blast inspection

Before proceeding to the blast site to carry out inspection, the Shot Firer or other competent person shall make an assessment to ascertain if it is safe to do so. The assessment shall include but not necessarily limited to, consideration of the following factors:

(a) Whether fume disposal has occurred.

(b) Whether dust dispersal/settlement has occurred.

( c) The identification of any apparently unstable grou~d.

( d) The stability of buildings and other structures.

( e) The safety and suitability of access and egress.

(f) Aspects of the blast that may indicate that not all of the charges have been initiated.

(g) In the case of a misfire, or a suspected misfire, whether the minimum waiting time has been observed. (no personnel in area for 5 minutes if initiation method was electric or signal tube, 30 minutes if safety fuse used)

(h) The availability of a competent person to inspect for safety, ground or material that did not move as it was intended.

29. Post-Blast Inspection

The purpose of a post-blast inspection is to ascertain if it is safe for personnel to return to the blast site and for routine operations to resume.

The extensive variables associated with not only the type of blasting operation but also the location of the operations would necessitate specific rather than general post-blast procedures to be included. The procedures for consideration should include but not limited to the following:

(a) Whether there is a need for more than one person to return to the shot for inspection.

(b) Procedures to be adopted if the inspection reveals that the "all clear' into the exclusion zone cannot be given, including the communications of the "all clear" or otherwise.

( c) Continuous inspection procedures during the approach to the post-blast site that might identify unusual or abnormal results indicating possible hazards.

( d) Identify a misfire or butt and the means of clearly marking misfires or butts.
