摘　　要：在塞尔维亚TMK铜金矿开拓系统施工中,除了出现涌水外,还出现十分罕见的涌气(H_(2)S)现象,为探究涌水、涌气原因,在开展矿区地表、钻孔岩心含(隔)水性、巷道等水文地质特征野外调查的基础上,结合相关技术文献资料,反复分析比对矿区地表水、基岩构造裂隙水、巷道涌水及相邻矿区涌水的水化学类型特征。研究表明:矿区水文地质结构自上而下依次为风化裂隙潜水含水层、隔水层、基岩构造裂隙含水层、溶蚀裂隙含水层;水文地质勘探类型并非前期地质勘查报告的“顶板直接充水的水文地质条件简单类型”,而是“矿床主要以顶板含水层充水为主,但在导水断裂构造区域顶、底板联合充水的水文地质条件中等偏复杂类型”。涌水来自深部碳酸盐类地下水、涌气(H_(2)S)来自地壳内部的岩浆活动产生的挥发组分,并阐明了H_(2)S气体向上漂移对矿区深部地下水补给、径流、排泄条件的影响作用,据此重新评价、估算了矿区水文地质条件、矿坑涌水量,以期为矿床开采设计提供更为可靠的水文地质技术参数。During the construction of the development system of the TMK copper-gold deposit in Serbia,in addition to water gushing,there is also a very rare gas gushing(H_(2)S)phenomenon.In order to explore the cause of water and gas gushing,on the basis of field survey of the hydrogeological characteristics of the surface in the mining area,borehole core water content(impermeability),roadway,etc.,combined with relevant technical literature data,repeated analysis and comparison of the characteristics of hydrochemical types for the surface water and bedrock structure fissure water in the mining area,tunnel gushing water and water gushing from adjacent mining areas,are carried out.The research shows that the hydrogeological structure of the mining area from top to bottom is weathered fissure phreatic aquifer,aquiclude,basement structure fissure aquifer,and dissolution fissure aquifer.The type of hydrogeological exploration is not reported by the previous geological survey as the simple type of hydrogeological condition where the roof is directly filled with water.But it is the medium to complex type of hydrogeological condition for that the deposit is mainly filled with water from the roof aquifer,and the top and bottom plates are jointly filled with water in the water-conducting fault structure area.The water gushing comes from deep carbonate groundwater,and the gas gushing(H_(2)S)comes from the volatile components produced by the magmatic activity in the earth crust.It also clarifies the influence of the upward drift of H_(2)S gas on the recharge,runoff,and drainage condition of deep groundwater in the mining area.Based on this,the hydrogeological condition of the mining area is re-evaluated and the amount of water inflow from the mine tunnel is estimated.It is expected to provide more reliable hydrogeological technical parameters for the mining design of the deposit.
