摘　　要：为了研究大平煤矿厚煤层在开采过程中的覆岩运移特征,以铁煤集团大平煤矿S2S9工作面综采工程为研究对象,利用数值模拟手段,对其工作面采动垂直应力场及位移场特征进行分析,得出顶板内岩层垂直应力等值线分布规律,岩层下沉特征及下沉量变化规律,揭示了工作面开采完成后地表下沉及水平移动特征。In order to study the overburden strata movement features during the mining process in in thick seam of Daping Coal Mine, the paper takes the mechanized mining engineering in S2S9 working face in Daping Mine as research object, and uses tile numerical simulation to analyze the characteristics of the vertical stress field and displacement field. The paper obtains the rock vertical stress contours distribution laws, rock sinking characteristics and subsidence variation laws, which reveals the surface subsidence and hori- zontal movement characteristics after mining.
