The exploitation of coal may cause surface subsidence. One can reduce the influence and damage for the environment if we predict the shape of the subsidence. Combining routine subsidence monitoring technology with geo-information technology and analyzing it, we put forward scientific evidence for control and administering the ecological environment of the mining area. The authors use the Feicheng mining area as the research area and analyze the dynamic change of it. The method provides a rapid and economic means for mining area subsidence monitoring.
