摘要
以神东矿区昌汉沟矿201浅埋深薄基岩工作面为研究背景,针对溃水溃砂发生机理及控制方法,采用现场调研、工程地质分析、数值模拟、现场试验相结合的方法,对该工作面溃水溃砂发生机理及控制方法进行了研究。从防止覆岩纵向贯通裂隙致灾、富水区域采前放水等方面,提出了多种针对性防治方法和综合措施,并在现场进行了应用。
Taking 201 coal workface in Changhangou mine of Shendong mine area as the study background, aiming at the mechanism and controlling methods of water inrush and sand inrush, using the methods of field research, engineering geological analysis , numerical simulation, field test to study on that. From the aspects of preventing the form of longitudinal through cracks, dewatering ahead of watery area, multiple specific controlling methods and comprehensive measures are raised, and applied in field production.
