采煤对矿山地质环境影响的预测评估——以阳泉三矿为例

Geological Environmental Impact Assessment Induced by Coal Mining:A Case Study of Yangquan No.3 Coal Mine

煤矿开采严重影响了矿区的地质环境,以阳泉三矿为例,分析了该区域地质灾害危险性、地下含水层破坏情况、地形地貌破坏情况和土地资源破坏情况,并对阳泉三矿地质环境进行预测和评估。评估认为,研究区地质环境破坏程度可分为严重区和较严重区,严重区面积为8.410 1 km2,占研究区面积的20.8%;较严重区面积为32.049 9 km2,占研究区面积的79.2%。

Coal mining has seriously affected the geological environment of the mining area. Taking Yangquan No.3 Coal Mine as an example, this paper analyzed the danger of geological hazards, the destruction of underground aquifers, the destruction of topography and landform and the destruction of land resources. And then the geological environment of Yangquan No.3 Coal Mine was predicted and evaluated. It was considered that the damage degree of geological environment in the study area could be divided into extremely serious area and more serious area. The area of the extremely serious area is 8.410 1 km2, accounting for20.8% of the study area;the area of the more serious area is 32.049 9 km2, accounting for 79.2% of the study area.
