摘要
根据参与同煤集团回采巷道锚网索支护技术规范编制的实践和体会,分析了制定锚网索支护技术规范的重要性和必要性,重点讨论了地质力学评估及回采巷道围岩稳定性分类、锚网索支护设计、锚网索支护材料与构件、锚网索支护施工及锚网索支护监测与信息反馈等规范内容的编制要点,同时归纳总结了锚网索支护技术规范在执行中可能存在的问题并提出了合理化的建议。
According to the practice and experience of compiling technical specifications for bolt-mesh-cable support in Datong coal mine group,the importance and necessity of formulating technical specifications for bolt-mesh-cable support are analyzed. The geomechanical evaluation and classification of surrounding rock stability in mining roadway,design of bolt-mesh-cable support,materials and components of bolt-mesh-cable support and anchor are discussed in detail.At the same time,it summarizes the problems that may exist in the implementation of the technical specifications of anchormesh-cable support and puts forward reasonable suggestions.
