Abstract In multiple-seam mining, severe deformation of roadways and coal bursts caused by overlying pillars can occur in the lower seams. Overburden movement ground pressure behaviour when mining thick seam below strong roof upper four extracted seams were investigated Tongxin mine, China. The numerical model indicated that abutment stress is affected as suggested bubble cantilever beam models...

Strong mine pressure has a great impact upon the safety production of coal mines. Microseismic information provides more advanced technical means for overburden fracture dynamic identification and mechanism research, since it contains rich on rock sources. In this study, isolated LW8102 working face in Tongxin Mine was investigated order to propose spatio-temporal microseismic event data analys...

Abstract Cases of landslides on clay shale slopes have been an intriguing study in Indonesia. Most the failed due to weathering rock. As studies focused properties shale, several FEM analyses indicated a unique translational type failure between interface and its overburden. However, modeling case was still limited. This aims evaluate landslide using thin-soil model software. The used two condi...
