煤矿巷道喷射砼“配比和强度”实验总结与分析

随着矿山建设的高速发展和矿井巷道支护技术要求的提高,特别是锚索主动支护的广泛应用,对于永久井巷、隧道支护面喷射砼工艺仍需要不断地实践与探索。根据多年中外矿井建设经验,对井巷施工喷射砼的"配比和强度"的进行了实验总结及分析,同时为其它类似矿井巷道在施工中提供了参考借鉴的经验。

With the development of mine construction and the rapid development of mine tunnel support technology requirement,especially cable active support is widely used,it is still needs to continue to practice and exploration for permanent tunnel,tunnel support surface spraying concrete technology.According to many years of foreign mine construction experience,summary and analysis the tunnel construction of spraying concrete 'ratio and strength' experiment,at the same time provides the reference of experience for other similar mine tunnel in construction.
