摘　　要：黑旺铁矿位于山东省淄博市境内，是年开采能力达几十万吨的露天矿。矿层位于中奥陶统的石灰岩中，为一多年平均日排水量达６．１２万ｍ３／ｄ的大水矿山。矿山所排出的水未受污染，但一直未得到很好的利用。矿山下游约１０ｋｍ处为一特大型的大武水源地，该水源地已超采，并且部分遭受污染。因此，该矿水的供排结合研究，对于缓解淄博市的供水矛盾有重要意义。本文在分析地质、水文地质条件的基础上，用逐步回归分析和多维时间序列分析，找出矿坑充水的主要因素，并预测矿坑涌水量；用有限元法计算允许开采量，预报矿山闭坑前后的水位；Heiwang Iron Mine, located in Zibo City, Shandong Province,is an open pit mine with annual mining capacity of several hundreds and thousands of tons. The ore beds are in the Middle Ordovician limestone.It is a water abundant mine with an average drainage of 61200 m 3/d, but the unpolluted drainage has not be utilized. There is a large water supply well field at Dawu,about 10 km downstream from the mine. At the well field, the groundwater has been over exploited and contaminated partly. It is very important for the local residents to combine water drainage with supply to mitigate the contradiction of local water supply.Based on the analysis of geological and hydrogeological conditions, we have studied the major control factors of mining water inrush, and predicted the quantities of mine drainage in the future by stepwise regression analysis and multi dimensional time series analysis; calculated the permissible mining yield and forecasted the groundwater levels before and after the mining period by finite element method;and evaluated the environmental influence after exploitating groundwater, and advanced a proposal for protecting the groundwater source.
