Abstract: Shenfu-Dongsheng coal field is located in the fragile eco-environment belt of the wind-water erosion crisscrossing region in northwestern Shanxi, northern Shanxi,and southern Inner Mongolia. Environmental destruction in the coal exploitation was so severe that safe production had been threatened. With large quantity of waste soil and residue piled up in the course of river and ditch way, water and soil loss both remarkably rose.Seepage of the groundwater and water level decrease by 2～3 m, even runoff cutting-off were causedby the 8 hm² ground sink in Daliuta coal mine zone.Great quantity of plant death, land should be piled for desertification, landslip and mud-rock occurred frequently.River sediment ation after the coal development was 5 times as thick as that before coal development. Proportion of thick sand in the river increased. River cross section reduced by 37.6%, and the ability of flood discharge lowered by 2 orders of magnitude. At the same time, the techniques for eco-system environmental administration should be set up in the coal field for the exploitation of coal mine and its sustainable development.
