Hedong coal field ajor coal-bearing strata Permian with Shanxi group normal development of No. 1 and No. 2 two layers of recoverable coal, interlayer spacing 5～20 m, No. 2 coal seam mining was influenced by No. 1 coal seam goaf water. Based on the problem, combined with successful water discharge of No. 1 coal seam goaf water in No. 2 coal seam mining of Baoli Yufeng Mining Industry, the water discharge was summarized, providing scientific data for solving similar water hazard of mine.
