【Abstract】 Lujiatuo Mining Branch of Kailuan Clean Coal Co. Ltd is currently the largest hydromine in the world and had gained remarkable benefits. But with the changing mining conditions, districts suitable for hydromining decreases. Now the mine is shifting its mining method gradually from hydraulic to conven tional method. How to ensure stable output and en hanced benefits during the transition period is of vital importance to the existence and development of the mine. The paper makes an analysis of the problems encountered in hydroming in -800m horizontal No.3 mining area of this mine, and proposes the specific countermeasures for enhancing hydroming capacity in thick coal seams.更多还原
