摘　　要：通过利用环境地质测绘、航卫片解译、山地工程、现场勘查、工程测量等技术手段和方法,对甘肃省崇信县新赤矿区煤矿采空引发的地质环境问题进行了较为详细的调查、研究和评价.研究区包括地面塌陷7处共3.6km2,崩塌和滑坡灾害7处共648.4×104 m3,泥石流沟8条共46km2,在引发地质灾害的同时还造成矿区地表水与地下水体污染、土地及植被破坏、水文地质条件改变等地质环境问题,严重威胁矿区及其下游约1.5万人、8.3亿元资产的安全.以上对我国同类矿山的地质环境研究与治理具有借鉴意义.Detailed investigation and research was conducted about geological environment problems in Xinzhou coal-mining area. These problems triggered by mining includes ground subsidence, rock-fall, land- slide, debris flow, pollution of surface and ground water, destruction of land and vegetation, change of hydrogeological conditions, which are a serious threat to the security of 14,703 residents and property worth 830 million yuan in the diggings and downstream areas. Some possible comprehensive measures are proposed to restore the geological environment of the area.
