摘　　要：煤炭开采加剧了矿区生态地质环境的恶化,导致矿区水资源和土地资源的破坏,同时诱发地质灾害,严重制约着煤矿区可持续、绿色发展。以某煤矿为例,在矿区地质环境现状调查的基础上,通过分析煤炭开采引起的地质环境效应,确定评价指标,建立基于可拓学理论的矿区地质环境效应评价模型,采用最优组合权理论确定评价指标权重,并对矿区地质环境效应进行综合评价,得出矿区地质环境效应评价分区图。评价结果表明:矿区生态弹性力脆弱,环境支撑力和资源禀赋较好,但煤炭开采对矿区地质环境产生较大不利影响,研究结果对矿区地质环境恢复保护具有重要意义。Coal mining has exacerbated the deterioration of ecological environment in mining area,which leads to the destruction of water resources and land resources in the mining area,and the occurrence of geological disasters,which seriously restricts the sustainable and green development of mining area.Based on investigation of the geological environment caused by coal mining,the evaluation index were determined,and the geological environment effect evaluation model of the mining area based on the extension theory was established and the index weight was determined by the optimal combination of empowerment.And the evaluation of geological environment effect of the mining area was carried out comprehensively,and the zoning of geological environment effect evaluation was obtained.The results showed that the ecological elasticity of the mining area was fragile,the environmental support force and the resource endowment were better,but the coal mining had a great negative impact on the geological environment of the mining area.The research results were of great significance to the restoration and protection of the geological environment in the mining area.
