湖北省南漳县范家岭铁矿水文地质条件及矿坑涌水量预测

Research of Hydrogeological Conditions and Prediction of Water Inflow in Fanjialing Iron Mine,Nanzhang County,HuBei Province

通过对矿区进行水文地质调查、钻探、抽水试验、地下水动态观测等手段,基本查明了该矿区的水文地质条件及矿床充水因素;确定范家岭矿区水文地质条件简单。分别采用地下水径流模数法、狭长水平坑道涌水量计算公式,对东、西单元矿坑涌水量进行了预测;对同类型矿床水文地质条件评价具有指导意义。

This thesis has ascertained the hydrogeological conditions of the mining area and main factors for deposit water filling over the hydrogeological investigation, probing, pumping test, drilling, dynamic observation of groundwater in tunnel and other methods. Fanjialing iron mine has simple hydrogeological conditions.. Groundwater runoff modulus method and the calculating formula are respectively adopted for the Water inflow in long and narrow tunnel to predict Water inflow in the east and west units. The method will guide us in evaluating hydrogeological conditions of the mineral deposit of the same kind.
