New progress in ground control monitoring system in Leeville underground mine1.45 Мб. The ground control monitoring system is composted of comprehensive instrument design and installations.In mining zones, the changes of ground conditions in critical locations with mining process are completely recorded by the ground control monitoring system.
Many mining operations have ground control departments staffed by specialist engineers and technicians. Underground openings are more difficult to create and maintain than rock or soil slopes, therefore underground mines generally must devote more resources and design efforts to ground control than surface mines and quarries.

This Bureau of Mines manual is intended to provide a better understanding of ground movement and the technology available for measuring it. The manual deals with convergence, strata separation, lateral roof movement, stress, and support load in underground mines. The instruments that measure these ground control parameters are described in detail.

Ground monitoring is essential in any underground mine. Ground Monitoring The earth is far from static; on the contrary, there is continual movement all the way from the surface to deep underground. While this movement is generally very slow, incremental and completely natural, it also can pose significant risks for those in the mining sector especially those who operate underground mines.
At Trolex, we develop intelligent strata control and monitoring instruments to help you protect employees, machinery and assets from rock fall and structural collapse. We offer a full range of solutions for underground mining operations, including longwall and room & pillar.
Rock Mechanics Ground Control Research Weak Rock Mass in Nevada Gold Mines: Behavior, Support Design and Performance. Many Nevada gold deposits are found in highly fractured, faulted, and argillised host rock (Brady et al., 2005) with Rock Mass Rating (RMR76) mostly ranging from 10 to 50 classified as weak to very weak rock under Bieniawski's (1976) rock mass classification system.

Timbering is also known as the conventional method of ground control. Timbers or posts are placed between the back and floor, usually against the sides. Crossbars span the posts along the roof, forming a three-piece set. This supports a wide area, such as a haulageway. Wedges are used to tighten the fit between the post and back or floor.
