Abstract: Abstract: SDIC Xinji Mine 210606 face by over 210806 face goaf water threat during the210606 face excavation, through the analysis, break the routine drilling escape mode is presented in -550m Shimen of track ahead of exploration drilling construction depression discharge 210806 face gob water solution. Practice has proved that: the use of depression ahead of exploration drilling put under negative pressure water Old Mining Area is entirely feasible, safe and easy to operate, good controllability, turn on the water flow stability, maintaining low operating costs, water drainage ahead of schedule, etc., under similar conditions ahead for the old Mining Area Drainage of water provides a valuable experience.
