摘要
为了查清试验场地的岩溶水文地质条件,减少或避免矿坑突水对矿山生产造成的危害,提高河南省灵宝市银家沟硫铁矿的开发利用水平和资源利用率,利用河南省三门峡市黑山沟Zj5孔漏水段进行了地下水示踪连通试验,通过示踪试验分析研究矿区岩溶地下水和硫铁矿Ⅲ号矿体井下导水断层上盘和下盘涌水点之间的水力联系,试验结果表明:Zj5孔附近岩溶地下水与Ⅲ号矿体断层上盘涌水点之间是连通的,连通的裂隙导水通道至少在二条以上,Zj5孔附近地下水与与Ⅲ号矿体断层下盘涌水点是不连通的,证明了试验场地区岩溶发育的不均一性和岩溶介质的非均质各向异性特征,为矿坑防治水工作提供了重要的水文地质依据。
In order to find out the hydrogeological conditions of the test site,to reduce or avoid the harm caused by mine water inrush to mine production and to make better the development and utilization of Yinjiagou pyrite in Lingbao of Henan Province as well as to promote the sound development and protection of mineral resources,the hydraulic connection between the karst groundwater near the grouting hole and the gushing points of the upper wall and the lower wall of the underground water-transmitting fault of No.Ⅲore body of the pyrite mine are analyzed and the groundwater tracer connection test is conducted by using the leaking section of the Zj5 hole at Heishangou Village in Sanmenxia of Henan Province.The test results show that the karst groundwater near the hole Zj5 is connected to the gushing point on the fault upper wall of the No.Ⅲore body,and there are at least two connected fissure water channels.The groundwater near the Zj5 hole is not connected to the gushing point on the fault lower wall of the No.Ⅲore body.It shows that the karst development in the test site area is uneven,and the karst medium is heterogeneous,which could provide the hydrogeological basis for the preventive treatment of the mining pit groundwater.
