Research on the control of overburden deformation by filling ratio

12.11.2022Underground resource exploitation has seriously damaged the surface ecological environment and underground water system. As an effective control measure, the filling mining process has greatly reduced the surface subsidence. As a branch of the filling mining process, the continuous mining and continuous backfilling (CMCB) method solves the contradiction of

19.11.2022It is also important to specify the time after which mining influences will no longer have a significant impact on the surface infrastructure and the environment. Analyses of the observed subsidence after the end of the mining operation indicate that this process may last from several months to several dozens or even several hundreds of years.

Drilling and Blasting in Underground Mining

202141Working safety in underground mining is related to blast operations, rock conditions and mining methods. The potential for roof problems, rock spalling, rock bursts, rock falls and brow damage is rife. It is a common problem that rock blasting in underground mines makes local underground water contaminated. The problem stems from two reasons.

2018214Impacts of underground mining Underground mining causes huge amounts of waste earth and rock to be brought to the surface – waste that often becomes toxic when it comes into contact with air and water. It causes subsidence as mines collapse and the land above it starts to sink. This causes serious damage to buildings.

THE EFFECT OF MINING GEOMETRY ON STABILITY OF ROCK

Stability was controlled by pre-failure brittle behaviour of rock. For squat pillars and low extraction ratio (selective extraction of a deposit), instability of the rock mass was on a global scale, manifested as shear movement or large scale collapse. Stability was controlled by post-failure ductile behaviour.
