贵州省煤矿生态环境影响评价分析

Analysis of Coal Mine Eco-Environmental Impact Assessment in Guizhou Province

选取贵州省封家营煤矿为研究对象进行生态环评,采用hpMSPS模式进行地表沉陷预测,结果表明:封家营煤矿地表沉陷最终最大值为6.6 m,地表变形影响范围为0.39 km2。由于矿区范围内地表坡度较大,煤炭开采所造成的地表沉陷表现形式主要还是以地表裂缝、局部塌陷、崩塌和滑坡等现象为主。在分析煤矿开采所引起生态环境问题的基础上,提出具体的防治措施,从而为贵州省煤矿生态环境保护和矿区可持续发展研究提供参考。

In this article, Analysis of Fengjiaying Coal Mine Eco-Environmental Impact Assessment in guizhou province, prediction of surface subsidence using hpMSPS model. The results show that the subsidence max value is about 6.6 m and the surface deformation range about 0.39 km^2 in Fengjiay-ing Coal Mine. Because of the large slope gradient in mining area, the subsidence forms is mainly a- bout surface crack, collapse and landslide phenomenon and so on. The article based on the analysis of ecological environment caused by coal mining, putting forward suggestions on reducing the nega-tive impacts from mining. The result provides reference for research in improving environment and sustainable economic development for guizhou province.
