LIU Wen sheng+1, SU Zhong jie\+2, WANG Sen lin\+2 (1\^Liaoning Technical University,Fuxin\ 123000,China; 2\^Tiefa Coal Industry Group Co.,Ltd.,Tiefa\ 112700,China)  
The forming condition and existing state of land collapse basins for shallow mining in a coal mine were investigated completely in this paper.The land collapse basins were divided into three types by use of the clustering analysis of fuzzy mathematics.The characteristics of surface subsidence and its harmfulness for the mine safety were analyzed.The preventive goal and principle to dispel the harmfulness of the land collapse for mine safety and to resume the environment of minefield were put forward.Four projects for harnessing land collapse basins were researched,namely ①removal of water from the collapse basin and the water\|resisting layer establishment;②subsidence basin reclamation;③subsidence basin for cultivating;④synthetic measures taken to suit local conditions.Through the implementation of these projects,the harmfulness of the surface subsidence for miness safety was dispelled completely and the environment of minefield was resumed.The ideal results and the social and economic benefits were gained.
