Abstract: There is a small amount of remaining residual water in north No.1 intake shaft of No.6 Mine after backwall grouting, which forms water spraying scattered and affects the effects of water control. By applying two years, the defects of using cofferdam groove closed water and tube parallel guide water combination method to control shaft water disasters is easy blockage and not easy to clean of aqueduct. Combined with the characteristics of shaft, the successful use of the cofferdam auxiliary tube closed water with single tube parallel concentrated water treatment method obtained good effect.
