散筋喷射混凝土是支护采矿巷道、修筑隧道衬砌和其它地下构筑物的最有发展前途的材料之一。同传统的喷射混凝土相比较,其优点已为大量试验数据及其在工业中的应用所证实。散筋喷射混凝土的物理力学性能和工艺参数最能充分地满足采矿巷道支护所面临的现代化要求,因此,采用这种轻型支护具有特殊的现实意义。全苏矿井建设组织及机械化科学研究所克里沃罗格分所研究出散筋喷射混凝土的新 Shotcrete is one of the most promising materials for supporting mining tunnels, tunnel linings and other underground structures. Compared with the traditional shotcrete, the advantages have been confirmed by a large number of experimental data and its application in industry. The physical and mechanical properties and process parameters of shotcrete tend to meet the modernization requirements of mine roadway support most adequately. Therefore, it is of special practical significance to adopt such lightweight support.
