Geotechnical Considerations In Underground Mines

Geotechnical Considerations in Underground MiningDepartment of Industry and Resources Guideline Document No. ZME723QT 1.0 INTRODUCTION The potentially hazardous nature of underground mining requires the application of sound geotechnical engineering practice to determine the ground conditions, the ground support and reinforcement requirements, as well as the size, shape and

Application Of Rock Reinforcement And Artificial Support

Application Of Rock Reinforcement And Artificial Support

Rock reinforcement and artificial support using rock anchors, rockbolts or dowels are becoming increasingly attractive as a viable technology for development of open pit mines. Both localized support and systematic pattern support can be used for significant reductions in mining costs through improved safety and increased slope angles.

The move towards larger underground excavations in both mining and civil engineering has resulted in the gradual development of cable reinforcement technology to take on the support duties which exceed the capacity of traditional rockbolts and dowels.

The smart mine of the future. The mine of the future is being built on connectivity. And the foundation of that is cellular technology. A private cellular network offers the most potential to transform mining operations by automating more processes, for example remote operations like autonomous haulers and drill rigs, plus the ability to monitor and automate heavy fixed assets.

It follows that the force displacement behaviour of each system is a consequence of the particular physical and mechanical characteristics of the system components and their ...
