回采巷道松软破碎围岩支护技术的探讨
|
摘要
结合马兰矿巷道支护实际情况,对松散破碎巷道掘进支护进行分析研究,对传统的巷道支护方案进行优化设计,提出"短掘短支+机载临时支护+永久支护优化"的联合支护方案。通过监测结果表明,该联合支护方案的应用可有效控制巷道围岩变形,达到良好的支护效果。
According to the actual situation of roadway support in Ma Lan mine, the paper analyzes and studies the tunneling support of loose broken roadway, and optimizes the design of traditional roadway support scheme. This paper puts forward the combined support scheme of "optimization of permanent support for short excavation and short support Airborne temporary support". The monitoring results show that the proposed combined support scheme can effectively control the surrounding rock deformation of the roadway, achieve a good supporting effect.
