Abstract：The abnormal emission of coal seam gas has an important influence on the safe excavation of roadway. Jingfu Mine is a high gas mine. In order to realize the safe excavation of 15109 cutting roadway in this mine, it is decided to carry out gas control by pre-drainage drilling in the heading head. The design of pre-drainage borehole in 15109 cutting roadway is analyzed, which mainly includes the design of pre-drainage borehole and the design of drilling anti-reflection construction parameters. The gas control scheme during the period of stopping excavation and pre-drainage is analyzed, which can provide some technical reference for the safe excavation of coal mine roadway.
