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 the 201 shallow buried deep bedrock face of Changhangou Mine in Shendong Mining Area as the research background, aiming at the occurrence mechanism and control method of the collapsible sandstone, the method of on-the-spot investigation, engineering geology analysis, numerical simulation and on- The mechanism and control method of collapsible sand on the working face were studied. Aiming at prevention of longitudinal disaster of overburden strata and drainage of water in pre-mining area, a variety of targeted control methods and comprehensive measures are put forward and applied in the field.
