摘要
随着煤炭资源不断开发,东部区域煤炭资源储量不断减少,煤炭开采逐步向西部区域转移。西部矿区的水文地质条件与东部截然不同,面临的水文地质问题主要为顶板巨厚砂岩含水层涌(突)水威胁;具有矿井涌水量随巷道开拓长度、开采面积增大而增加,多个充水含水层,采动导水裂缝带发育高度较大、导水能力强等水文地质特点。总结了西部典型矿区顶板巨厚砂岩水防治的多年工作经验,提出了防治水工作"三个体系"和防治水"十法",实施效果良好,可为西部矿区进行顶板巨厚砂岩含水层防治技术研究提供参考。
With the continuous exploitation of coal resources,the reserves of coal resources in the eastern region are decreasing.Now the exploitation of coal resources is gradually transferring to the western region.The hydrogeologic types in the western mining region are quite different from those in the eastern region.The main types of water hazards are thick sandstone aquifer water in coal roof,characterized by the continuous increase of mine water inflow.Mine water inflow increases with the length of roadway development and mining area;there are many aquifers filled with water;mining water-conducting fractured zone develops high.According to the analysis of field measurement and water quality test data,the mining water-conducting fractured zone is highly developed and has strong water conductivity.In order to study the characteristics of the thick sandstone aquifer in the roof and its water control methods,the hydrogeological conditions and water control methods in the relevant areas were studied.
