摘要
Abstract
Taking the No.5 mine in Dananhu mining area of Xukuang Group Hami Energy Co.,Ltd.as the research object,by using the underground upward hole water injection leak detection method and borehole TV imaging method to measure the development height of the"three zones"of the overlying rock,combined with various methods such as theoretical prediction,physical similarity simulation,and numerical simulation,the development law of the water conducted zone in the weakly cemented soft rock roof of the main No.22 coal seam was comprehensively compared and analyzed,and the expected parameters of the mine water conducted zone were proposed and derived.The research result can provide a basis for mine water hazard control and safety production under weakly cemented rock mining conditions,which has a significant promoting effect on improving mine production efficiency and releasing production capacity.关键词
