刘园子煤矿井筒修复治理

摘要

Aiming at the destroying situation of shaft in Liuyuanzi coal mine , combines with the hydrogeological conditions of shaft , by analysis ensures that the main reason of Liu Yuanzi mine shaft destruction is geostress and acid -ic water erosion .Puts forward the main idea of shaft control of crush resistance and yielding .The mainly means of shaft repair and treatment are walling crib reinforcement , grouting behind wall and pressure relief groove .The preven-tive measures taken in the actual construction of complex mine shaft are summarized .%针对刘园子煤矿井筒破坏现状，结合井筒水文地质条件，通过分析确定刘园子煤矿井筒破坏的主要原因为地应力和酸性水侵蚀，提出井筒治理的主要思路为“抗压和让压”，井筒修复治理的主要手段有井圈加固、壁后注浆和卸压槽，并总结了水文地质条件复杂矿井在井筒实际施工中采取的预防性措施。
