山东省东平县大高庄铁矿矿床充水因素分析及涌水量预测

摘要

Dagaozhuang iron deposit is a large middle sized sedimentary metamorphic iron deposit.Through hydrogeology survey,reformer information and hydrogeology survey of underground tunnels,hydrogeo-logical characteristics and water filling source of this deposit have been found out.It is showed that its hydrogeological boundary condition is simple and hydrogeological condition is medium type.Combining with actual water inflow,by using the "long and narrow adit method " and " big well method ",normal water inflow and largest water inflow at different elevation have been predicated.It can provide reliable ba-sis for deposit in deep mining.%大高庄铁矿为中型沉积变质型铁矿。通过对区内地表水文地质调查、前人工作资料的收集、以及井下坑道水文地质调查，查明了矿床的水文地质特征及充水来源，确定其水文地质边界条件简单，水文地质条件属于中等；结合目前矿坑实际涌水量，采用“狭长水平坑道法”与“比拟法”对不同标高矿坑正常涌水量和最大涌水量进行预测，为矿床的开采提供可靠依据。
