Abstract

In order to acquire the rock strata movement rule above the coal face, which has shallow buried depth and thin bedrock, choosing the 201 dip working face of chang han gou coal mine, Shenhua group, as the engineering background. Using numerical simulation software UDEC, which has distinct elements, to do simulation analysis about the structure destruction rule of rock strata above working face and the sliding and unstable movement regularity of the main roof. This paper shows that the whole overlying rock strata of mining face falls by full thick and the ground subsides sharply when the first weighting of the main roof has happened. And with the advance of mining face, the overlying rock strata sinking phases. These simulated results are consistent with the field breakage of rock strata above the mining face. So the software UDEC can provide prospective theory basis for mining activities.
