With the large-scale mining of coal mines,more environmental geological problems were caused,among which coal mining subsidence was one of the most common environmental geological problems in mining areas.In this paper,taking Yangchangwan Mine as an example,through the investigation of ground subsidence situation in the goaf of the mining area,the scope of the subsidence area and the influence degree were evaluated.Combined with the mining continuation plan,the ground subsidence deformation caused by medium and long-term coal mining was analyzed and predicted,and the prevention and control countermeasures were put forward.The study had certain guiding significance for guiding the prevention of mine geological disasters,the restoration of mine ecological environment and the creation of green mines.
