| Abstract: | When the phenomenon power failure or suddenly hit the high pressure water zone appear in the process of constructing water drainage boreholes，closing stop valve was unable to plugging of drilling water by pulling out the drill pipe. Aiming at this problem，borehole sealing device in exploration and drainage of hydraulic drillhole drilling was developed in the paper. It can realize the quick plugging of drilling water in the case of not pulling out the drill pipe. The field application shows that the device has high reliability，and it can ensure the safety of the construction. |
