磨槽江铅锌矿地质环境影响评估及防治对策

Geological Environmental Impact Assessment and Prevention Countermeasures of Miaojiang River Mine

磨槽江铅锌矿是以裂隙充水为主的矿山,其主要开采矿体远高于当地河水面之上,为了评估磨槽江矿区在恢复开采后对矿山地质环境的危害,从矿坑涌水量、矿区围岩支护、矿坑沉陷、含水层、地表水污染程度五个方面研究矿山开发引起地质灾害出现的环境影响综合评估。结果表明,恢复采矿后矿坑的涌水量小、矿坑围岩稳定性高,对矿坑地面沉陷和含水层流场的影响程度一般,且不会对周边居民的生活水源造成污染。

grinding groove River mining area is filled with fracture water of the mine,the main mining body is much higher than that of the local river waters,in order to evaluate the grinding groove in the recovery of river mining area after mining mine geological environmental hazards,comprehensive environmental impact assessment from the water inflow of mine,mine,mine rock support subsidence,aquifer,the surface water pollution in five aspects of mining development caused by geological disasters occur. The results show that after mining,the water inflow of mine pit is small,the stability of mine surrounding rock is high,and the influence degree of mine surface subsidence and aquifer flow field is general,and it will not pollute the living water source of the surrounding residents.
