According to soft coal seam with large gas content and gob water, large water level fall, water drainage difficulty in 21004 working face of Dongpang Mine, through analyzing hydrology, geology and comprehensive gas conditions, a feasible and safe water drainage scheme was studied and formulated, which discharged water in working area effectively and ensured safety on the roadway excavation. The technology provide experience for exploration mined water discharge under complex conditions in the future.
