Based on the analysis for the geological disasters in front and behind the ending of the mining in open-pit coal mine,summarized the disasters of the environment geology problem,mainly have three aspects:① The deep big pit and dump due to open cut mining will form.② As a result of the geologic structure,the rock mass in slope,the function to the surface water and groundwater,mining engineering activities,and other factors,open cut mining formed the pit slope and the dump slope induced a series of sudden or slow geological disasters such as sliding,to cave in,mud-rock flow,surrounding ground deformation.③ Open cut mining induced deterioration of the ecological environment and the slow change characteristic disasters.Put forward the methods used in environmental geological disasters danger by zones after the ending of mining in open-pit coal mine.According to above study,taking by zones of environmental geological disasters danger of Fushun Western Open-pit Coal Mine after the ending of mining as an actual case,obtained results conform to the actual.
