肃北县敖包沟金矿矿山地质环境问题及恢复治理措施

Mine geological environment problems and restoration measures of Aobaogou Gold Mine in Subei County

肃北县敖包沟金矿区位于生态环境脆弱区,在矿产资源开发的过程中,为了切实保护和利用各类矿产资源、减少矿业活动对周边环境的扰动,加快矿山地质环境恢复和综合治理已刻不容缓。以肃北县敖包沟金矿区为研究对象,通过资料收集与分析、野外实地调查、综合研究等方法,对矿山的开采规模、范围、工程等级、工程布置及矿山开采方式等进行了分析,认为地质环境问题主要表现为矿业活动对地形地貌景观破坏、易引发的地质灾害问题、对地表土地的占压和破坏。针对具体问题,通过危岩清理,平硐口采取支护、设立挡石墙、斜井回填、弃渣平复等工程手段,以消除或减轻地质灾害隐患,达到对矿山的地质环境保护与恢复治理。

Subei County Aobaogou gold mining area is located in the fragile ecological environment,in the process of mineral resources development,in order to effectively protect and use all kinds of mineral resources,while reducing the disturbance of mining activities to the surrounding environment,accelerate the recovery of mine geological environment and comprehensive management has no time to delay.Taking Aobaogou gold mining area in Subei County as the research object,this paper analyzed the mining scale,scope,engineering grade,engineering layout and mining mode of the mine by means of data collection and analysis,field investigation and comprehensive research.It was considered that the problems of geological environment are mainly manifested in the destruction of landform and landscape,the geological disasters easily caused by mining activities,and the occupation and destruction of surface land.In view of the specific problems,through the dangerous rock cleaning,the adit mouth to take support,set up retaining wall,inclined shaft backfill,waste slag flat rehabilitation and other engineering means to eliminate or reduce the hidden dangers of geological disasters,to achieve the protection and recovery of the mine geological environment.
