针对峰峰矿区煤层采深大,承受奥灰岩溶水水压高,隐伏导水构造类型多,赋存条件和探测条件复杂的水文地质环境,分析研究峰峰矿区奥灰岩溶水突水资料和水文地质特点以及对开采的影响,提出了工作面底板注浆加固与改造技术,奥灰含水层顶面注浆加固技术,裂隙、断层、陷落柱含导水构造通道治理技术,水平多分支井技术,水害监测预警技术等奥灰岩溶水水害综合治理技术方案,实践证明该配套技术可有效防范奥灰岩溶水水害。

According to the Fengfeng Mining Area's hydrogeological environment of large coal seam mining depth, high water pressure of the ordovician limestone karst water, varied concealed conductivity structure type, complicated occurrence and detection conditions, based on the analysis of the ordovician limestone karst wat er burst data and hydrological geology characteristics of the Fengfeng Mining Area and the influence on mining, formed a set of technology of ordovician limestone kars t water disaster management which including coal floor grouting reinforcement and reconstruction, ordovician limestone aquifer top grouting reinforcement, crack, fault, collapsing column water transmitting channel governance, horizontal and multi-lateral wells, water disaster monitoring and early warning, the practice proved that the m atching technology could effectively prevent the ordovician limestone karst water disaster.
