摘要
在对封闭形全圆可缩性支架进行力学分析和实验室力学性能检验的基础上，论述了金属可缩性支架的工作特性和缺陷，进而介绍了软垫层与金属可缩性支架联合支护软岩巷道的原理和在沈阳三台煤矿工程应用中的技术经济效果，为软岩巷道提供了一套较为实用的支护办法。
On the basis of analyzing and inspecting mechanics property of compressiblesupport,this paper points out the performance characteristics of metal compressible sup-port,it also introduces the support principle of soft rock roadway in which soft cushion andmetal compressible support are jointly used. Furthermore,it enumerates the technical andeconomic results achieved in Santai Mine of Shenyang.
