李雅庄煤矿2号煤层存在太原组灰岩岩溶水带压开采问题,参考近期矿区水文地质勘查成果和矿井的突水资料,介绍了太原组灰岩含水层的水文地质概况,并详细阐述了其岩性组合特征、测井物性特征、钻探水文特征、地下水流场特征等,表明矿区南部由于受断裂构造、应力集中、岩石破碎等因素影响,太灰含水层富水性较强,而矿区北部太灰含水层富水性较弱。最后从5个方面总结了矿区南部太灰含水层富水性强的具体原因,以期为以后的煤矿研究提供宝贵的借鉴。
Based on the results of recent hydrogeological exploration in the mining area and water inrush from coal mines, the coal seam No. 2 in the Liyazhuang Coal Mine has the problem of limestone karst water pressure mining in Taiyuan Formation. The hydrogeology of the limestone aquifer in Taiyuan Formation is introduced, and its rock The results show that the southern part of the mining area is affected by the fracture structure, stress concentration and rock fragmentation and other factors, the water-rich aquifer is too strong, while the northern part of the mine is too gray Aquifers are less water-rich. Finally, the specific reasons for the strong water-bearing capacity of the Tai-Ash aquifers in southern mining area are summarized from five aspects in order to provide valuable reference for future coal mine research.
