鲁山县下寺铅锌矿采矿活动对矿区地质环境的影响分析及恢复治理研究

A Research on the Influence of Mining Activities on Geological Environment andRestoration of Xiasi Lead-zinc Mine in Lushan County

鲁山县下寺铅锌矿因采矿活动,形成的废石堆场、矿石堆场、工业场地、高位水池、矿石道路等,共造成土地损毁面积0.9096 hm 2。通过对矿区进行地质灾害危险性现状评估、水土环境污染现状评估,结果显示矿山开采对地质环境影响程度较轻,对水土环境污染影响程度较严重;通过对废石堆场、矿石堆场、工业场地、高位水池、矿石道路等现状评估,认为矿山开采对地形地貌景观破坏影响较严重。将评估区划分为重点、次重点和一般防治区,开展矿山地质环境治理与土地复垦工程,力求将地质环境影响程度降至最低。

Due to mining activities,we find that the waste rock yard,ore yard,industrial site,elevated pool,ore road,etc.in Xiasi Lead Zinc Mine of Lushan County have caused a total land damage area of 0.9096 hm 2.Through the assessment of the current situation of geological hazard risk and water and soil environment pollution in the mining area,the results show that the mining has less impact on the geological environment and more serious impact on the water and soil environment.In the assessment of the status quo of waste rock yard,including ore yard,industrial site,elevated pool,ore road,etc.,it is considered that mining has a serious impact on the landform and landscape.The assessment area is divided into key areas,sub key areas,and general prevention and control areas.We have carried out the mine geological environment treatment and land reclamation projects to minimize the geological environment impact.
