摘要
根据深部大断面切眼巷道的地质和生产技术条件,对复合顶板条件下的切眼巷道支护方案进行了优化设计,通过数值计算分析及现场跟踪观测,提出了锚梁网索加架棚联合支护方案,该方案显著改善了切眼受力状况,取得了比较好的支护效果。
According to the geological and production technology conditions of large section cutting hole in deep well, the article designed supporting schemes of composite roof for large section cutting hole, by using numerical analysis and and field tracing observation,gived com- bination supporting scheme of anchor beam nets cable add JiaPeng, the scheme was improved significantly condition of cutting hole stress , and achieved good supporting effect.
