Abstract: This article will introduce the gray model to prediction of mining land use change，make use of 3 phases of TM data in Pingshuo mining area，combine with the actual characteristics of mining land use，divided 7 kinds of land use type：the arable land,forest & grass land，industrial and residential land，water，transportation land，to be reclaimed land，unused land，analysed and studyed the gray model method and the solution process in Pingshuo mining land use.Prediction results show that：arable land decreased，it is expected to reach 18 173.21 hm2 in 2023，percent for 45.4% of the total mining area;At the same time，the to be reclamated land formed by the collapse land and dump land gradually increased，it is expected to reach 3 849.62 hm² in 2023，Therefore，the strength and progress of land reclamation should be increased，to promote change from the reclamated land to arable land as soon as possible，and harmonize the change speed between production building and ecological building on land-use.to ensure the sustainable use of various types of mining land

Key words: Grey prediction model, Land use, Mining area
