摘要
针对大采高作业面过断层的片帮控制开展研究,结合具体工程实际,在分析断层处片帮机理的基础上提出针对性的综合防治措施,实现了断层处煤壁稳定性的有效控制,保障了生产作业的正常推进。
This paper studied the control of rib spalling during passing through faults at working face with large mining height and put forward the targeted comprehensive control measures based on the analysis of the mechanism of rib spalling at faults section combined with engineering practice,which realized the effective control of the stability of coal wall in the fracture and guaranteed the normal progress of production.
