It is very important to obtain accurate land use changes data in coal mine area for making land use planning and land reclamation policy. The traits of CA (Cellular automata) such as strong complicated computing capability, inherent parallel computing capability, highly dynamic characteristic and spatial concept, etc. , have made it very strong on spatial-temporal evolution modeling of the complex system. CA is applied to simulate and predict land use spatial structural evolution in mine area because of its characteristics. But it is very different for land use changes in coal mine area in terms of urban growth. Coal area growth can be divided into four stages, whose evolution rules are different from other areas. Traditional CA model cannot satisfy this demand because of its static transition rules. In view of different characteristics of land use changes in every stage of coal mine, an improved CA model based on the lifecycle theory for coal mine area is proposed to simulate and predict the changes of land use in mine area. This improved model allows the users to select appreciate transition rules according to stages. To test the efficiency of the model, the Changcun coal mine in Lu'an mine area is chosen as a study area. By collecting remote images and other data, considering the characteristics of the according stages in Wuyang and Shihejie coal mine, the model is used to simulate and predict the land utilization evolution of mature period and declining period in Changcun mine area. It is demonstrated by the actual case 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 mine area.
