Abstract: The accurate simulation and prediction of the land utilization evolution of mine, is an important basis for determining the land use planning, land reclamation measures. Taking into account of the superior performance of the cellular automaton model (CA) in the land-use modeling and prediction, the CA model is introduced to the simulation and prediction of the evolution of land utilization. But it is very different for land use changes in coal mine area from urban regions. The high tension exploitation of coal resources is one of the important elements that affect the evolution of land utilization. Based on the basic principles of coal resources development, EMMLCA (Evolution Model of Mining-induced Land Based on CA）model of land use evolution under coal mining is established to simulate and predict the changes of land use in mine area. To test the efficiency of the model, the changes of land use in Lu'an coal mine area is simulated and predicted based on EMMLCA model. Result shows that the model is both feasible and effective, thus its predicted results can be taken as accurate and reliable data for the land use plan of coal mining area.
