Study on Close Coal Seam Pressure Behavior Law of Zhong Xing Mine by Physical Model
Based on the actual geological data of the 1202 lower layer work face of the Zhong Xing mine, in Shanxi province, a physical similar simulation model has been built to analyze the influence on the lower coal layer after mining the upper layer, and research on the deformation, failure law and the stress distribution of overburden rock. The results show that after mining the upper coal layer, overburden rock experienced subsidence, separation, bending and even breaking down, and the original state of the rock destroyed. The rock's intensity is weaken, and the whole rock has been softened. When the distance of the coal layers becomes smaller, the influence of the mutual exploitation becomes larger. Those results provide a reference for reasonable layout of the mining of the coal seam working face.
