摘　　要：无为县西湾多金属矿水文地质钻探的目的是大致查明工作区的水文地质条件,通过开展水文地质钻探,利用先进的钻探工艺,配置优质冲洗液,解决第四系水敏垮塌及岩溶施工的难题;水文地质孔钻至目标层位后并成井,进行抽水试验,获取含水层水文地质参数,并判断目标层富水性。The purpose of the hydrologeological drilling in the Xiwan polymetallic ore deposit in Wuwei County is to determine the hydrogeological conditions of the working area,and solve the problems of water-sensitive collapse in the Quaternay strata and construction in karst using advanced drilling process and high quality flushing fluid.After the borehole reaches the target layer and a well is completed,a pumping test is carried out to obtain the hydrogeological parameters for judging the water yield property of the aquifer.
