Simulation analysis on overlying strata movement rule in shallow buried coal-seam after mining operation

摘要：

　　In order to obtain overlying strata movement rule of mining shallow buried coal-seam, taking the productive working face in third coal seam in Yulin as the engineering background.Analogue simulation was made to analyzing it from three conditions which are change of displacement, crack evolution and mining stress.The experimental results obtained three-zone characteristic of shallow buried coal-seam, mine pressure characteristics and strata displacement characteristic, which provided reference for safe mining of coal-seam with similar geological condition.
