In order to solve the problem of insufficient discharge of traditional underground water damage prevention and control in a coal mine,the application research of advanced drilling technology in the increasing underground discharge water was carried out.The geological and hydrological characteristics of the coal mine were explored and analyzed by the test analysis method,and the layout,track and structure of the boreholes of the advanced drilling technology were analyzed.The borehole construction parameters was determined from multiple angles to realize the application of advanced drilling technology in increasing discharge water in the coal mine.The application results showed that the discharge water before the application of the technology was 654 987.489 m3,and the discharge water after the application of the technology was 962 600.881 m3,which indicated that the advanced drilling technology has a good application effect in the prevention and control of water damage in the coal mine.
