“三软”全煤顺槽桁架锚杆支护技术研究

Study on Truss Bolt Support Technology in "Three-soft" Coal Roadway

摘要:

煤矿软岩巷道是很难支护的巷道，其支护问题一直困扰着煤矿的生产和建设。从理论上分析了桁架锚杆系统的作用机理，并针对“三软”全煤巷道的特点，制定了全煤顺槽桁架支护方案。通过试验，取得了良好的支护效果。

Abstract:

It is very difficult to support the coalmine soft-rock tunnel.This paper theoretically analyzes the mechanism of truss bolt system, and gives the design of coal roadway support according to the characteristics of the "Three-soft" coal roadway.Good supporting effect was achieved by test.
