| Abstract: | Combined with Daliu coal mine overburden 11 mining area actual situation, using the probability integral method, we forecast the surface deformation after coal seam mining, and draw the surface subsidence isoline map and analyze the influence degree and scope of the surface subsidence on the surrounding environment. Based on these work this paper puts forward the prevention measures. It provides a reference for the prevention and treatment of production subsidence in Daliu coal mine in the future. It is also helpful to carry out similar research work in this area. |
