龙塘沿铁矿水文地质特征及防治水对策

Hydrogeological Characteristics and Water Control Measures of Longtangyan Iron Mine

龙塘沿铁矿是一座岩溶裂隙直接充水矿床,水文地质条件复杂。采用三维渗流模拟系统,建立了龙塘沿铁矿水文地质模型,预测了矿坑涌水量,结果表明I期正常涌水量2796.9m^3/d,Ⅱ期的正常涌水量1825.5m^3/d;提出了近矿体帷幕防治水措施,并对技术经济的可行性进行了验证。

Longtangyan Iron Ore is a karst fissure direct water-filling deposit.The hydrogeological characteristics are complex.3D transfusion simulation system is used to establish the hydrogeological model for Longtangyan Iron Ore.It predicts the water inflow of the pit.The results show that the normal water inflow is 2796.9m^3/d in phase I.and the normal water inflow is 1825.5m^3/d of phase II.It put forwards the water control measures of curtain grouting of ore body.It also verifies the feasibility of technology and economy.
