摘要
针对某矿2022运输顺槽大断面全煤巷道的围岩控制问题,本文充分利用现场调研、矿压观测、统计分析等研究方法,分析了巷道围岩变形及失稳冒落的原因,通过提升改良锚索的支护参数对原支护方案进行优化,并进行了现场试验及后续围岩变形监测,实现了巷道围岩的有效控制,保障了安全生产。
In view of the surrounding rock control problem of a mine 2022 transportation gateway with large cross-section and full coal roadway,this paper makes full use of research methods such as field investigation,mine pressure observation and statistical analysis to analyze the causes of roadway surrounding rock deformation and instability and caving,optimizes the original support scheme by improving the support parameters of the anchor cable,and carries out field tests and subsequent monitoring of surrounding rock deformation,thus realizing effective control of roadway surrounding rock and ensuring safe production.
