麦垛山矿矿井水害分析与防治

Research on Maiduoshan Coal-mine Impermeable Layer Characteristics and Groundwater Recharge and Discharge Conditions

根据相邻矿井的统计发现麦垛山矿较为稳定的隔水层有:直罗组底部砂岩含水层顶板的粉砂岩、泥岩为主的隔水层、各主要煤层及其顶底板泥岩、粉砂岩组成的隔水层。在此基础上,对麦垛山矿矿井水文地质条件进行了综合分析,确定矿井开采2-2号煤期间水文地质类型为复杂型,而由于麦垛山矿处于建井后期和生产初期,矿井永久防排水系统尚未完全建成,矿井抵御水害能力尚显薄弱,加之矿井水文地质勘探深度和广度不足,为此,针对性地提出了今后防治水害的一些具体措施。

According to statistics of the adjacent Maiduoshan Coal -mine is more stable impermeable layer： the bottom of the Zhi- luo sandstone aquifer roof sihstonc, mudstone aquicludc, the main coal seam and its roof and floor mudstone, siltstonecomposed of aquifuge. On this basis, Maiduoshan Coal - mine of hydrogeological conditions, a comprehensive analysis to determine underground mining of the No. 2 - 2 coal during the hydrogeological type complex, Maiduoshan Coal - mine in the late well construction and pro- duction of the early mine permanent drainage system has not been fully completed, the mine to resist water damage is still significantly weak, coupled with the lack of depth and breadth of mine hydrogeological exploration end, the author puts forward some specific meas- ures for controi of water disasters in the future.
