The Deep Mining 2014 Committee and the Australian Centre for Geomechanics have worked for many months with industry to generate an exciting and focussed technical programme that brings together leading visionaries, strategists and experts from local and global industries.

The objective of this series of international seminars is to promote discussion and documentation of the latest technologies and practices of mining in deep and high stress environment. Since inception, the technical content has focussed on geomechanics issues with themes such as seismic monitoring, ground support and numerical modelling dominating the proceedings. Nevertheless, the seven seminars also offer an important contribution to the more traditional mine engineering themes of deep mine planning and design, as well as ventilation.

Associate Professor Marty Hudyma, Laurentian University, and the ACG team look forward to joining with our Canadian friends and peers to host Deep Mining 2014 in Sudbury.

APPLICATIONS OF SEISMIC MONITORING IN MINES COURSE 13 September 2014 | Courtview East Room | Radisson Hotel Sudbury

This one day course consists of two parts:

Part one covers basic principles of seismic monitoring and conventional applications of the data for mining practices. This comprises an overview of seismic monitoring systems and data processing techniques. Special attention is paid to the limitations of seismic data - pollution of seismic catalogues by blasts, uncertainty in location of seismic sources, effect of sensor type and usable bandwidth on source parameters, sensitivity of source mechanisms to sensor orientations. The data processing techniques and applications are illustrated using IMS software.

Part two of the course is focused on one specific application - integration of stress modelling with seismic monitoring. This includes forensic analysis of rockbursts and large seismic events, validation and improvement of numerical stress models using seismic data, simulation of seismicity and incorporation of seismic data in numerical models.

The course attendees will receive a temporary licence of IMS software, which can be downloaded from our web site and installed on their

laptops. The demonstration seismic databases and corresponding 3D visualisation/analysis projects will be provided as well.

We trust the course will help mining geotechnical engineers comprehend both the limitations and benefits of seismic monitoring for their routine tasks.

#Attendees must bring a modern laptop (running Windows 7/8) to participate in hands-on components of the workshop. Attendees will be provided with a short-term licence for ESG software and an example dataset for a hands-on tutorial.

The purpose of this workshop is to demonstrate how seismic data from any type of mine site can be used to help understand the rock mass response to excavation. Underground mining continues to reach for minerals deeper in the Earth and to develop more aggressive mining methods, both of which significantly contribute to higher stress levels and therefore elevated seismic activity.

Today’s high accuracy seismic technology provides a database with a large magnitude range including many smaller magnitude events from which trends can be assessed to help explain the rock mass reaction from small scale fracture initiation to large fault slip.

The advanced analysis of a single event or a cluster of microseismic events has become one of the main tools incorporated into rock mechanics analysis and mining strategies. Event source mechanism stress inversion analysis and the benefits to stress model calibration will be presented and discussed.

This workshop begins with a short introduction to seismic concepts, followed by practical examples of seismic analysis methods. Attendees with laptops will be provided with a short term licence version of ESG software and an example dataset.

Safety statistics from Canada, Australia, Chile and Sweden are showing that the mining world has become very skilled at operating safely in high seismic hazard conditions. Often, the last line of defence to control seismic risk is the installation of a dynamic resistant ground support system. The performance of ground support exposed to dynamic loading has been the subject of intense research and numerous trials during the past decade. Many new products are now available on the market. There are increasingly more data and experience generated from the mines using these products. This experience and knowledge needs to be shared in a workshop environment. Furthermore, intense laboratory testing programmes on ground support have been ongoing at Canmet in Ottawa.

The focus of this workshop will be on sharing the valuable experiences gained with dynamic support. The workshop will allow for discussion periods to facilitate exchanges on some of the key topics related to dynamic resistant ground support systems.

The main objectives of the workshop are to review the most recent progress and technology development on dynamic ground support, and to offer a forum for practitioners and researchers to share their experiences and discuss relevant dynamic support issues; from the design of support systems to their performance when subjected to large seismic events.

PRACTICAL CALIBRATION OF NUMERICAL MODELS FOR MEANINGFUL PREDICTIONS OF GROUND BEHAVIOUR COURSE19 September 2014 | Notre Dame Room | Radisson Hotel SudburyNumerical modelling is an important tool for mining geomechanics. When properly calibrated, numerical models are capable of simulating mine plans in order to predict rockmass deformation, the severity of seismicity and potential for rockbursting over the mine life. These predictions can then be used to identify potential risk for damage to critical mine infrastructure, and for ensuring personnel safety. This one day course will provide participants with the necessary tools for qualitative and quantitative model calibration so that forward simulations of mine plans can provide meaningful predictions of ground response to mining.

SITE VISITS


SITE VISIT: CREIGHTON MINE, VALE CANADA LTD.Underground Tour of Creighton Mine’s Deep Operations

19 September 2014Creighton Mine is located 20 km west of Sudbury, and is one of the six underground mines being currently operated by Vale. The mine has been in production since 1901, and currently operates at a depth of 2,470 m and its present extraction rate is approaching 3,500 tonnes per day. As is expected from a mine in production for more than 100 years, several mining methods were used at Creighton. In the upper area, blastholes, cut-and-fill, and vertical retreat mining have been used. Today’s most economically important area of the mine is located below the 6400 level (1,950 m) and is known as Creighton Deep, where high magnitude seismic events have occurred due to the mining depth and the presence of major seismically-active structures. In order to reduce the seismic risk to As Low As Reasonably Achievable (ALARA), the mine is actively using various control measures, including a unique mining method of a pillarless slot-and-slash and a top-down centre-out sequence, an identification of high seismic risk areas by using Hazard Mapping Techniques and the use of various dynamic ground support systems.

SITE VISIT: NICKEL RIM SOUTH MINE, SUDBURY INO, A GLENCORE COMPANY19 September 2014Sudbury Integrated Nickel Operations’ activities include Fraser Mine and Nickel Rim South Mine, Strathcona Mill and the Sudbury smelter. The company has been mining nickel-copper ores in the Sudbury area of northern Ontario, Canada, since 1929. The facilities are spread throughout the 60 km long, oval-shaped geological formation known as the Sudbury Basin. Nickel and copper are the primary metals but cobalt and precious metals, such as gold, silver, platinum and palladium are also produced. Sudbury INO currently employs more than 1,300 permanent employees.

The production rate is 1.25 Mt/ year. Featuring shaft access, its current orebodies are 1,160 to 1,710 m below surface. Nickel Rim is a primary/secondary open stoping operation.

Please note that spaces are limited to 18 people only.
