With the development of economy, human activities on energy demand increases.Coal,which is important energy, has been large-scale exploitation and utilization in recentyears. Coal mining plays an important role in enormous economic benefits,at the sametime,it also brings the geological environmental problems which is can not be ignored.Ground subsidence is one of the main coal mining geological environment issuescaused by the land and buildings, and caused more serious influence and destruction. Inorder to achieve the purpose of environmental protection, the research of mining subsidenceprediction and management appears particularly important.Based on the coal mine as an example, in the mining subsidence prediction, and putsforward the corresponding control measures, and on two methods of governance effect werecalculated. Its main contents are:(1) introduced the basic situation of the coal mine. Introduced the system of grounddeformation and influence factors of mining subsidence.(2) the use of probability integration method and ANSYS on mining subsidence forecast. Adetailed introduction of the ANSYS software in mine mining subsidence., and obtainsmore accurate forecasting results.(3) the prediction based on the results, put forward for the coal mine management method:filling method and the boundary method of reinforcement.(4) the use of ANSYS on the boundary strengthening method treatment effect are explained,using ANSYS and mechanical computation shows that the control effect of fillingmethod. Through the mechanics formula when the filling process and filling rate of acertain100%, filling material stiffness on filling effect plays a major role in governance.At this time, the filling material stiffness and reducing subsidence is roughlyproportional to the.
