山东能源枣矿集团柴里煤矿作为我国第一对厚含水冲积层下开采厚煤层的试验矿井,随着矿井服务年限的不断延长,采空区面积不断增加,受特殊地质构造的影响,老空区内的顶板砂岩水、防灭火注浆水无法自然流出,造成了老空区内积水。柴里煤矿克服采空区点多面广等重重困难,通过引进新技术、新工艺,拓展隐患排查治理途径,有效治理了老空区积水、井筒渗涌水等矿井隐患,保障了矿井的安全生产,为今后防治水工作顺利开展积累了宝贵的经验。
As the first pilot mine in China to mine thick coal seam under thick aquifer alluvium, Chaili Coal Mine of Shandong Energy Zaozhuang Mining Group, with the continuous extension of mine service life, the area of goaf increases continuously. Affected by the special geological structure, Sand roof area of the water, fire extinguishing grouting water can not be natural outflow, resulting in the water area empty. Chaili Coal Mine to overcome the mulching area point wide and so on many difficulties, through the introduction of new technologies and new processes, to explore ways to improve the hidden trouble investigation and management of the empty ground water, borehole infiltration of water and other mine hazards to protect the safety of the mine , Which has accumulated valuable experience for the smooth implementation of water control work in the future.
