The impact ground pressure is currently restricted mine production and safety of one of the typical dynamic disasters, this paper USES the two-dimensional evaluation method from two dimensions of risk and possibility analysis of the impact of the situation in a coal mine in shandong province, using fault tree (FTA) to determine the impact, with grey correlation analysis to find out the key factors that affects the risk impact and to improve the traditional fault tree analysis method, effectively solve the traditional fault tree in uncertain complex system are not suitable for as a quantitative analysis of the defects Combined with the field mining simulation of Shendong Group to judge the stress concentration and migration, to assist in verifying the impact risk of Shendong Coal Mine, the multi-parameter early warning system combining geological factors and mining factors is established, and the key factors of impact risk are corrected.
