摘要
为了对五彩湾矿区一号矿井地下水环境影响进行评价,对该矿井的水文地质条件和水质现状进行了分析和评价。研究结果表明:根据研究区含水岩组的分布特征以及富水性,可以划分为五个含水岩组和一个相对隔水岩组,其中具有供水意义的含水层为第四系松散岩类孔隙含水层,该含水层主要接受东南部侧向径流补给,地下水由东南向西北方向径流,以向西北侧向径流及蒸发的方式排泄;研究区第四系松散岩类孔隙水水化学类型主要以SO_4·Cl-Na、Cl·SO_4-Na和Cl-Na为主;基于地下水水质标准指数法和内梅罗指数法评价结果,研究区地下水水质总体较差,水中多项评价因子超标,超标原因主要由蒸发作用强烈、放牧和野生动物活动,以及区内北部卡拉麦里山地下水的影响。
In order to evaluate the impacts on the underground water environment of No.1 mine in Wucaiwan mining area,this paper analyzes and evaluates the hydrogeological condition and current situation of water quality of the mine.The results are as follows：according to the distribution characteristics and water-abundance of aquifer groups in the area,the aquifer groups can be divided into five aquifer groups and a relative water-resistance group.The aquifer with significance of water supply is porosity aquifer in quaternary period.The aquifer is mainly supplied by the lateral runoffs in the southeast.The underground water runs off from the southeast to the northwest and drain through the lateral runoffs in the northwest and evaporation.The hydrochemical type of porosity aquifer in quaternary period in the area are mainly SO_4·Cl-Na,Cl·SO_4-Na and Cl-Na.The results are assessed based on underground water quality standard index method and Nemerow index method.The water quality of underground water in the area is poor in general.Many assessment factors in the water exceed standard.The reason of exceeding standard is due tothe strong evaporation,pasturing and wildlife activities as well as the impacts of underground water from Karamori mountain in the north of the area.
