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。It is very difficult to support the eoalmine 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.
