Abstract 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.
