刘冲磷矿是个开采二十多年的矿山,三个主要矿体的开采都已进入地下水位线以下,其中规模最大的Ⅰ号矿体北段已深达243米。从开发中揭露的水文地质问题看,是目前国内磷矿床开采中较复杂的。因此,正确评价矿区水文地质条件,认真总结治理矿坑水的经验,或许能起到抛砖引玉作用。 The Liuchong phosphate mine is a mine that has been mined for more than 20 years. The mining of the three major ore bodies has been below the groundwater level, with the deepest No. I orebody in the northern section reaching 243 meters deep. From the development of hydrogeological problems exposed, it is more complicated in the domestic exploitation of phosphate deposits. Therefore, the correct evaluation of the hydrogeological conditions in the mining area, conscientiously sum up the experience of treatment of pit water, may play a valuable role.
