摘要
复合顶板条件下的煤巷施工,给支护工作带来很多困难,如不采取先进合理的支护技术方案,将可能产生很大的安全隐患。文章主要从支护方式选择、锚网索支护原理、支护参数设计及实际应用等方面进行分析和研究,并对如何确保复合顶板条件下锚网索支护质量及安全问题进行了阐述,现场实践证明,锚网索联合支护方式具有良好的技术经济效果。
The Coal roadway construction under condition composite roof,to brings a lot of support difficulties,if not taking advanced reasonable supporting technology solutions,will likely have a huge security risk.This article from the support mode selection,anchorage supporting principle,support parameter design and the practical the application aspects makes an analysis and research,and describes how to ensure that anchor support quality and safety the composite roof.The practice show that anchor mesh combination support has good technical and economic results.
