Ground Support

Advanced Ground Support in Underground Mining

Perth, Western Australia, May 2007

ACG Course Number: 0703

Presenters: J. Albrecht (AMC Consultants Pty Ltd), S. Bailey (Coffey Mining), D. Beck (Beck Arndt Engineering), E. Bernard (Technologies in Structural Engineering Pty Ltd), M. Clements (Grenz Consulting Pty Ltd), P. Dight (Coffey Mining), D. Gaudreau (BHP Billiton Nickel West), R. Hawker (Minova Australia), D. Heal (ACG), B. Kinsella (Curtin University), M. Moore (Yuleba Minerals), D. O’Toole (Xstrata Mount Isa Copper Mines), Y. Potvin (ACG), M. Sandy (AMC Consultants Pty Ltd), S. Saydam (University of New South Wales), G. Sharrock (University of New South Wales), W. Wiggin (Basalt Consulting Pty Ltd).

Readership: This course was designed to inform ground control and mining practitioners of the latest developments in ground reinforcement and support in underground mines. Topics covered were: ground support under dynamic loading and in highly deformable ground, shotcreting issues and innovation – in cycle shotcrete and early re-entry, synthetic and steel fibres, update on thin spray-on liners, numerical modelling of ground support, corrosion, minimising blast damage and also case studies.

Topics included:

  • Ground Support in Highly Deformable Ground (and time dependant behaviour)
  • Dynamic Loading of Ground Support
  • Shotcreting issues and innovations:
    • In-cycle shotcrete and re-entry time
    • Shotcrete arches
    • Quality control
  • Numerical Design of ground Support
    • Displacement Based Design
    • Use of Block Model
    • Non-linear modeling
    • Use of Tecto-Genesis
  • Thin Spray-on Liners
  • Reinforcement corrosion
  • Minimising Blast Damage
  • Ground Support Issues in Mine Shafts
  • Case studies

 

Ground Support in Mining

Perth, Western Australia, October/November 2006

ACG Course Number: 0607

Subseries: Ground support

Presenters: Dr Phil Dight (Coffey Mining), Professor Yves Potvin (Australian Centre for Geomechanics), Wayne Robertson (CSIRO), Ian Walson/David Lehane (Atlas Copco), Des Vlietstra (Elastoplastics), Adrian Moore (Jacon Technologies), Peter Jenkins (Dempers & Seymour), Jody Todd (BHP Billiton), Richard Butcher (Barrick Gold), Brett Ascott (Newmont Australia).

Readership: The course was designed to assist mining personnel involved with the design and implementation of mine ground support. Also benefiting from the course were mine managers, mining engineers, mine geologists, mining supervisors and operators, suppliers of mine support equipment, mining contractors and mines inspectors.

This course was developed to cover both the technical and practical aspects of ground support for underground and open pit metalliferous mines.

Topics included:

  • Types of ground instability in underground and surface excavations.
  • Mechanisms of reinforcing and supporting rock.
  • Bolting alternatives and their relative performance.
  • Support design techniques including practical constraints on design.
  • Support installation methods and minimum standards of installation quality.
  • Quality assurance programs.
  • Support costs and monitoring the support design.
  • Rockfalls and mine seismicity in underground mines.
  • Ground support in highly deformable ground.
  • Case studies from the coal and metalliferous industries.

Each topic was illustrated by case history examples from surface and underground mines.

Ground Support in Open Pit and Underground Mines

Perth, Western Australia, April 2005

ACG Course Number: 0503

Subseries: Ground support

Presenters: Dr Phil Dight (BFP Consultants Pty Ltd) and Professor Yves Potvin (Australian Centre for Geomechanics)

Readership: The course was designed to assist mining personnel involved with the design and implementation of mine ground support. Also benefiting from the course were mine managers, mining engineers, mine geologists, mining supervisors and operators, suppliers of mine support equipment, mining contractors and mines inspectors.

This course was developed to cover both the technical and practical aspects of ground support for open pit and underground metalliferous and coal mines.

Topics included:

  • Types of ground instability in underground and surface excavations.
  • Mechanisms of reinforcing and supporting rock.
  • Bolting alternatives and their relative performance.
  • Support design techniques including practical constraints on design.
  • Support installation methods and minimum standards of installation quality.
  • Quality assurance programs.
  • Support costs and monitoring the support design.
  • Rockfalls and mine seismicity in underground mines.
  • Ground support in highly deformable ground.
  • Case studies from the coal and metalliferous industries.

Each topic was illustrated by case history examples from surface and underground mines.

International Seminar on Surface Support Liners: Membrane, Shotcrete and Mesh

Perth, Western Australia, August 2001

ACG Course Number: 0104

Presenters: Alan Thompson (Alan Thompson Technology), David Ortlepp (SRK S.A.), Dwayne Tannant (Uni. Alberta), Ernesto Villaescusa (WASM), Chris Windsor (Research Engineer), Dick Stacey (Uni. Witwatersrand), John Hadjigeorgiou (Laval Uni.), Kugan Kaganathan (MIM), Samantha Espley (Inco), Chris Langille (Golder), David McGowan (Black Swan), Stephen Duffield (Northparkes), Mathew Watt (Placer Dome), Christopher Irwin (BHP Cannington), Sam Spearing (MBT), Rob Hawker (Fosroc), Neville Henderson (Mondi), David Finn (WMC), Jan Kuijpers (CSIR Miningtek), David Laurence (Uni. of NSW), James Archibald (Queen's Uni.).

World-wide experts with extensive practical experience within the surface support liner industry discussed the proficiencies of customary surface support liners, novel applications, state-of-the-art technologies and compared the different materials. The main outcome of this series of international seminars on surface support materials (South Africa 2002 and Canada 2003) will be the membrane testing 'guidance and advice handbook'.
Attendees benefited from Australian and international case studies on how mining operations can improve efficiency, lower their costs and maximise the safety of resource recovery through the application of surface support liners.

All presentations were based on research and projects undertaken by leading companies including their operational work at local and international mine sites. Each topic contained both practical and technical information to assist the attendees to select the appropriate work practice and technology to improve their mine's performance and productivity.
