摘　　要：通过改变地表形态和降低土壤质量,井工煤矿生产对土地产生比较严重破坏。影响井工煤矿破坏土地的因素较多,针对所评估煤矿,煤层埋深与开采厚度、水文地质条件通常是主要因素,因此,选用土地利用类型、地表破坏程度和地面积水状况三个评估指标,采用单因素分析和叠加分析的方法进行土地破坏危险性评估。Through changing the configuration of the earth＇ s surface and debasing the soil quality, land has been badly damaged in undergrund mines. There are many factors of affecting land damage in underground mines, thickness and depth of coal extraction, properties of hydrological geology are primary factors to the evaluated underground mining, as risk evaluation on land damage, three evaluating indexes of land use style,damaged degree of the earth＇s surface and seeper degree on ground are selected, Single factor analysis and stacking analysisare adopted.
