坎上铁矿水文地质特征及涌水量预测

Research on hydrogeological features and prediction of yield of well of the Kanshang iron mine

在水文地质勘查的基础上,指出坎上铁矿分成南北2个矿段,赋存于复杂的水文地质条件中,包括4个含水层和2个弱透水层。利用大井法和数值模拟法对矿区的涌水量进行预测,结果表明本阶段概算单独开采至矿体底板时,北矿段正常涌水量为3 067m3/d,南矿段正常涌水量为23 400m3/d。

Large amounts of hydrogeologic survey data show that the Kanshang iron mine is divided into 2 parts, under complicated hydrogeologic conditions with 4 aquifers and 2 aquitards. With the methods of big-well and numerical simulation, yield of well is predicted. The result is that the normal yield in the north part is 3 067m^3/d, 23 400m^3/d in the south part.
