摘要
煤矿开采完出现的地质环境灾害问题的治理及生态修复工作任重道远,我国大部分矿区属于井工开采,煤层开采完上覆岩层会出现垮落、地面塌陷,隔水层破坏导致含水层水大量渗漏到采空区,造成地表水资源流失;煤炭开采过程中伴随着伴生气体资源的释放,受采动充分卸压,煤层气体完全释放、富集、积聚到采空区,形成井下煤层气资源;且井工开采过程中会产生很多地下空间资源。因此,研究分析了煤矿开采完采空区区域产生的各种地质灾害和环境问题,并提出相应的整改措施。
The management and ecological restoration of geoenvironmental disaster problems after coal mining is a long way to go. Most of the mining areas in China belong to shaft mining, the overlying rock layer will collapse and the ground will cave in after coal mining, and the destruction of the water barrier will lead to a large amount of water leakage from the aquifer to the mining area, resulting in the loss of surface water resources;the process of coal mining is accompanied by the release of associated gas resources, which is fully unloaded by mining, and the coal seam gas completely released, enriched and accumulated to the mining area, forming underground coalbed methane resources;and the process of well-working mining will produce many underground space resources. Therefore, the study analyzes various geological hazards and environmental problems arising from the impact of coal mine finished mining void area area, and proposes corresponding rectification measures.
