摘　　要：Water disaster is one of the most important types of disasters in coal mines. In the past, most of the water prevention methods adopted in coal mines have some problems, such as large construction quantity, large demand for personnel, long construction period, and inability to prevent in advance. In order to effectively solve this problem, it is necessary to explore an economical, practical and efficient sidetracking technology, which can not only save the construction period, reduce the amount of hole sealing materials, simplify the construction steps, reduce the frequent tripping operations before and after sidetracking construction, but also reduce the cost. In this paper, the rapid sidetracking technology of branch drilling applied in water disaster control in Zhaogu No.1 Coal Mine is studied.
