摘要
以澄合二矿24506大跨度切眼断面锚杆(索)支护项目为工程背景,运用理论计算、数值分析和现场监测相结合的手段,对复合顶板大跨度切眼支护技术进行了研究和现场实践,得出复合顶板大跨度切眼支护较为合理的支护参数。
With the engineering background of Chenghe second coal mine 24506 long-span cut cross-section bolt support project,by combining of the theoretical calculation,the numerical analysis and the practical monitoring,the supporting technical research and analysis of site support monitoring in large span cut of composite roof are carried out,reasonable supporting parameters in large span cut of composite roof are obtained,experiences and references are provided for the future design of similar roadway.
