中文摘要	神府东胜煤田地处晋陕蒙水蚀风蚀交错的生态脆弱带,开发中出现的环境问题已威胁到矿区生产安全.大量弃土弃渣堆积于河道与沟道,加剧了水土流失;大柳塔等矿发生8hm2的塌陷与地裂缝,引起地下水渗漏,水位下降2～3 m,甚至断流;大量植物死亡,土地沙化日趋严重;人为滑坡、泥石流活动频繁;河道泥沙变粗近5倍,粗沙比例增加,淤积使过水断面减少了37.6%,行洪能力降低了2个数量级.通过对弃土弃渣集中排放,扰动土回填复垦,植树造林的措施建立矿区环境整治技术体系,根本改变生态环境使矿区生产持续稳定地发展.
英文摘要	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. Envi-ronmental 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 Diiliuta coal mine zone. Great quantity of plant death, land should be piled for desertification, landslip and rnud-rock occurred frequently. River sediment ation after the coal development was 5 times as thick as that before coal development. Pro-portion 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.
