摘  要:针对麻家梁煤业公司14104工作面顶板涌水水害问题,利用矿井井上下地质条件综合立体探查技术以及矿井顶板水疏放防水技术,进行水害防控研究设计。通过分析工作面水文地质情况、探查顶板砂岩富水情况,揭示富水区域主要集中在顶板冒落裂缝带发育范围内,进而施工钻孔对富水区进行疏放水。14104工作面经过约两个月的疏放水工作,工作面顶板单孔涌水减少至10 m~3/h以内,钻孔水压控制在安全标准1.2 MPa以下,钻孔涌水量趋向稳定,表明顶板水害疏放技术设计合理,效果良好。Aiming at the problem of water inrush on the roof of the 14104 working face of Majaliang Coal Industry Co.,using comprehensive three-dimensional exploration technology to explore the geological conditions above and below the mine shaft,as well as the drainage and waterproofing technology for the roof water of the mine,the author researches and designs water disaster prevention and control,reveals that the water rich area is mainly concentrated within the development range of the roof caving crack zone by analyzing the hydrogeological conditions of the working face and exploring the water rich situation of the roof sandstone,and decides to carry out drainage and water release in the water rich area through construction drilling,whose application results show that the water inflow of the borehole tends to be stable,and the design of the roof water disaster relief technology is reasonable and good,with the water inflow from a single hole on the working face roof reduced to within 10 m/h,and the drilling water pressure controlled below the safety standard of 1.2 MPa.
