洛宁县龙门店银矿矿山环境地质问题及综合治理措施研究

Study on environmental geological problems and control measures of Longmendian Silver Mine in Luoning County

河南省洛宁县龙门店银矿位于熊耳山多金属成矿带,矿区采矿活动频繁,对周边的环境造成了严重的影响,随着国家对绿色矿山建设的加快推进,矿山地质环境恢复和综合治理已刻不容缓。以洛宁县龙门店银矿区为研究对象,通过矿山地质及地质环境调查,分析了矿山的开采规模、地貌环境特征、环境影响范围、地质灾害引发方式等因素,初步认为地质环境问题主要表现为矿业活动对地形地貌景观的破坏、引发的地质灾害、对地表土地的占压等。针对矿业活动引发的地质环境问题,采取相应的地质灾害防治和土地复垦工作,进行地裂缝防治、矿井回填、土地治理复垦,最大限度地避免或减轻因矿山工程建设和采矿活动对矿山地质环境的影响和破坏。

Longstorem Silver mine,Luoning County,Henan Province,is located in Xiong′er Mountain polymetallic metallogenic belt.Mining activities in the mining area are frequent,which has caused a serious impact on the surrounding environment.With the acceleration of green mine construction by the state,the recovery and comprehensive management of the mine geological environment has become urgent.In this paper,longstorem Silver mining area in Luoning County was taken as the research object.Through the investigation of mine geology and geological environment,the mining scale,geomorphic environment characteristics,environmental impact range,geological disaster initiation mode and other factors were analyzed.It was preliminarily concluded that the geological environment problems are mainly manifested in the destruction of landform and landscape by mining activities,geological disasters easily caused,and the occupation and destruction of land surface.In view of the geological environment problems caused by mining activities,geological disaster prevention and control work was carried out,ground crack prevention and control,mine backfilling,land management and reclamation,so as to avoid or reduce the influence and destruction of mine geological environment caused by mine engineering construction and mining activities to the maximum extent.
