摘　　要：在超千米深井筒施工中,一般受厚冲积层淋水及高承压含水层淋水的威胁或影响。对肥矿集团井筒深达超千米的梁宝寺煤矿二水平井筒施工中,封堵高承压井筒淋水的注浆工艺、技术参数、浆液材料选择及井筒涌水变化规律进行总结研究,为超深立井开展井筒淋水灾害治理提供参考。In the construction of super-kilometer deep mine,it is generally threatened or influenced by the drenching water of thick alluvium and drenching water of high bearing aquifer.The grouting process,technical parameters,slurry material selection and the change law of wellbore water gushing were summarized and studied in the construction of the second level wellbore of Liangbaosi Mine,which had a wellbore depth of more than 1,000 meters,the technology provided reference for the management of wellbore water gushing disaster in super-deep vertical mines.
