摘　　要：肥城煤田水文地质条件极为复杂,煤层开采受徐灰水、奥灰水威胁严重,注浆封堵徐灰岩溶裂隙,增加煤层周边岩层的有效隔水层厚度,隔绝徐灰水与奥灰水的水力联系,已成为肥城矿区解放受徐灰水威胁的煤层、实现安全开采的重要技术措施。文章介绍了肥城矿区注浆改造含水层的技术经验。The hydrogeological condition of Feicheng coalfield are extremely complex,mining operation subject to Xu limestone water and Ordovician limestone water threat,grouting technology to closing karst fissure of Xu limestone water,increase effective thickness of the separation layer of coal seam surrounding rock,isolated from hydraulic connection of Xu limestone watewater and Ordovician limestone water. The paper become important technical measures to liberation of coal by Xu limestone water threat and achieve safe mining in Feicheng coalfield.
