摘要
煤矿水害的防治对于煤矿安全开采十分重要。结合阳煤集团寿阳开元矿业的地质情况,对其未来开采过程中可能的水害进行探讨。首先分析了井田的水文地质条件,主要是含水层和隔水层的分布情况;然后重点分析了矿井的充水条件;最后探讨了未来开采过程中可能发生的水害。研究结果表明,该矿3号煤层开采时会贯通上部砂岩裂隙含水层,9号煤层开采受上部砂岩含水层裂隙水和采空区积水影响,可能形成矿井涌水,但不会威胁矿井安全;15号煤层虽受岩溶水水害影响,不会威胁矿井安全。
The prevention and control of coal mine water damage was very important for coal mine safety mining.Combined with the geological conditions of Shouyang Kaiyuan Mining Industry of Yangquan Coal Group,the possible water damage in the future mining process were discussed.Firstly,the hydrogeological conditions of the mine field were analyzed,mainly the distribution of aquifer and aquifuge;then we focused on the analysis of the water filling conditions of the mine;finally,the possible water damage in the future mining process were discussed.The research results showed that the mining of No.3 coal seam in this mine would penetrate the upper sandstone fissure aquifer.The mining of No.9 coal seam was affected by the fissure water of the upper sandstone aquifer and the water accumulation in the goaf,which might form mine water inflow,but would not threaten the safety of the mine.Although No.15 coal seam was affected by karst water damage,it would not threaten mine safety.
