| 摘 要： | 为保证矿区安全开采，采矿本身要求排出大量的矿井水，这不可避免地使附近的地下水水位下降，并可能影响到已有地下水水源地的供水安全，产生供、排水矛盾。本文以淮北市徐楼铁矿为例，用数值法分析评价矿坑排水对城市供水安全造成的影响，并对越流系数的不确定性进行了定量分析。分析结果表明：矿坑排水对徐楼水源地引起的水位附加降深最大值为0．0244m，仅为水源地设计开采水位降幅（6．0m）的0．41％，对附近地下水水源地的供水安全造成的影响较小，不会影响到水源地的正常运行。

| Abstract: | Lots of mine water pours out during period of mining to ensure the safe mining. However, it is inevitable to decrease the groundwater level around the mining area and even to influence the water supply safety of the constructed groundwater source fields. As a result, the conflict between water supply and mining drainage happens. Therefore, in this paper, a case study of Xulou iron ore in Huaibei City was taken to evaluate the effects of mine drainage on the urban water supply in safety. Besides, uncertainty of the coefiqcient of leakage was also analyzed in quantity. The study results show that the maximum additional drawdown of water level is only 0.0244m, which is only 0.41% of the designed drawdown. Therefore, there is a little effect on the water supply safety. |
