Abstract: In view of the shendong mining area of water conservation mining technical problems, in the system analysis part to solve water problems filling mining based on the theoretical analysis, laboratory test and numerical simulation methods of filling process, This paper puts forward the research ideas and methods to solve the problem of water conservation mining with green partial filling mining .The main conclusions are as follows: (1) part of the filling of water conservation mining mechanism、analyzes the technical characteristics、the filling process; (2) derived partial backfill method, meet the water resisting key layer does not break the relationship; (3) according to the layer theory and the effective area of water resisting key theory derived mining and stay wide; (4) the numerical simulation results show that partial filling parameter selection of height of water flowing fractured zone has important effect. Study in Shendong mining area were carried out on-site implementation, related research has certain reference significance and application value to the similar conditions of coal mining water.
