摘要
破碎顶板巷道是井下回采中一种常见的形式,实现对该类巷道围岩变形的有效控制,对于提升巷道使用安全性意义重大。结合工程实际,在分析矿井原支护方案不足的基础上,分析了改良后锚索架棚联合支护工艺的应用,并探究了应用效果。结果表明,优化后的支护工艺实现了对破碎顶板巷道围岩变形的有效控制,提升了巷道掘进速度和施工效率。
The broken roof roadway is a common form in underground mining. The effective control of the surrounding rock deformation of this type of roadway is of great significance for improving the safety of roadway use. Combined with the engineering practice, based on the analysis of the shortage of the original support scheme of the mine, this paper analyzed the application of the improved combined support technology of anchor cable shed and explored the application effect. The results show that the optimized support technology can effectively control the surrounding rock deformation of the broken roof roadway, and improve the tunneling speed and construction efficiency.
