| 摘 要： | 山东省济宁铁矿埋藏在济宁群变质岩中,铁矿石资源量约18.34亿t,因埋深在1 000m以下,开采条件较差,为查明水文地质条件,施工了1 500m深的水文地质勘探孔,在此基础上进行了抽水试验,取得了水文地质参数。通过数值模拟预测了-1 200 m,-1 300 m,-1 400 m,-1 500 m开采水平的正常矿坑涌水量分别为998.56 m~3/d,1 079.27m~3/d,1 159.98m~3/d,1 240.68m~3/d,为开采可行性研究提供了水文地质数据。

| Abstract: | Jining iron deposit in Shandong province is buried in metamorphic rocks of Jining group. The iron ore resources are about 1.834 billion tons. Because the buried depth is below 1000m, and the mining condition is bad, in order to identify hydrogeological condition, hydrogeological exploration drilling holes with the depth of 1500m have been constructed. On these basis, pumping test has been carried out, and hydrogeological parameters have been gained. Through numerical simulation, it is predicated that normal mine water inflows at the depth of 1200m,1300m,1400m,1500m are 998.56m3/d, 1079.27m3/d, 1159.98m3/d, 1240.68m3/d respectively. It will provide hydrogeological data for feasibility study of mining. |
