摘要
为了进一步提高底板岩溶水害区域治理技术的有效性,降低底板突水的危险性,解决区域治理过程中治理层位选择、治理模式和安全治理范围的确定等安全技术问题,基于冀中能源多年底板水害区域治理工程实践,通过深入分析邯邢矿区近年来区域治理后工作面出水案例,提出了奥灰区域治理层位选择的基本原则;针对多个复合含水层(段)条件,构建了地面顺层治理与井下穿层治理相结合的底板岩溶水害多层"三维立体"区域综合治理新模式;给出了在几种不同构造条件下工作面安全治理范围的计算方法。并在峰峰矿区梧桐庄矿水文地质条件极复杂182602工作面水害治理中进行应用实践,取得了良好的治理效果,对类似条件下底板岩溶水害区域治理工作具有很好的借鉴意义。
In order to further improve the effectiveness of the regional treatment technology for Karst water damage,reduce the risk of water inrush on the floor,and solve safety technical issues such as the choice of treatment level,treatment model,and safety governance range during the regional governance process,based on the practice of the energy-damaged regional water pollution treatment project for many years in Jizhong Energy Group,through in-depth analysis of the water treatment cases at the working face in recent years in the Hanxing mining area,the basic principles for the selection of the treatment level of the limestone water area were proposed;A new model for comprehensive management of multi-level"three-dimensional"area of Karst water damage on the floor combined with ground bedding treatment and underground penetration treatment was presented.The calculation method of the safety treatment range of working face under several different structural conditions was given.In addition,it has been applied in the treatment of water hazards in the extremely complex hydrogeological conditions of No.182602 Wutongzhuang coal mine in Fengfeng mining area,and has achieved good control results.It has a good reference for the regional treatment of floor karst water damage under similar conditions.
