摘要
通过井下现场实验得出了快硬水泥竹锚杆的工作特性曲线及其工程特性。在此基础上，提出了将竹锚杆用于软煤巷道支护的锚喷支护方案，井用５００多ｍ试验巷道验证了其可靠性。图２，表４，参３。
Through underground tests,the displacement force curve under the workingcondition and other engineering propertiea of the fast cement bamboo rockbolt are ob-tained. Based on it,this paper presents the design that uses rockbolts in which most arebamboo ones and shot concrete to support the opening in soft coal.The reliablity of thesupport system has been proved by the test opening with more than 500m in length.2fings.,4tabs, 2refs.
