大冶铁矿铁门坎采区深部开采地下水涌水量预测

The Water Yield Prediction of Groundwater in Deep Mine in Tiemenkan Mining Area in Daye Iron Mine

通过广泛调查大冶铁矿铁门坎采区的水文地质情况,从水文地质条件、充水情况等方面研究影响铁门坎采区地下水涌水量的因素,同时运用"大井法"计算矿坑-230m中段涌水量,结果证明了该方法应用的可行性。因此,运用"大井法"可以进一步对矿山深部开采-350m中段的涌水量进行预测,从而为矿山进行深部开采和防治水措施的施行提供了一定价值的参考意见。

This paper discusses the influence factors of the water yield of groundwater in Tiemenkan mining area of Daye iron mine in the aspects of hydro-geological conditions, filling conditions etc. We use ＂large diameter well method＂ to calculate the water yield of the pit in --230m level center section. The calculation result proves the feasibility of this method. Therefore, we can predict the water yield in --350m level center section, thus providing valuable references for deep mining and implementing measures of water proofing in mines.
