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
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.
failure that occur in rock masses around underground openings. 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.

This includes the Proceedings of the international symposium, Abisko, Sweden, 28 August-2 September 1983. Rock bolts today represent the dominant support system in mines and underground structures. Some results and experiences are discussed to give a better understanding of the strength of individual rock bolts and systems of bolts, and

Oct 01, 2019 Fig. 4 is a conceptual representation of the capacities of rock reinforcement patterns used in seismically-active mines. These capacities were calculated based on the load and energy capacities of individual rock reinforcement elements and their installation patterns as part of ground support systems at Mines A, B and C.
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.

These developments form part of the continuous improvement evident in support and reinforcement practice in underground mining.
Rock Reinforcement versus Rock Support By COL W. B. ERWIN ... Early mining operators worked under the correct assumption that an unknown quantity of rock in the ceiling and shoulders of an excavation acted upon the supports as a dead load, plus a live load during blast-ing. They knew that a firm contact had to be main-

Sep 01, 1997 Essentially, support is the application of a reactive force at the face of the excavation, and includes techniques and devices, e.g. fill, timber, steel or concrete sets, shotcrete, etc. Reinforcement is considered to be an improvement of the overall rock mass properties from within the rock mass and will therefore include all techniques, and ...

Sep 02, 1996 A terminology for reinforcement practice is proposed based on the idea that a reinforcement device, a rock mass and a reinforced rock mass are all systems of components. 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 ...

As will be shown in this chapter, the primary objective of support practice is to mobilise and conserve the inherent strength of the rock mass so that it becomes self-supporting. The procedures and materials used in this case may be more correctly described as reinforcement .
