为实现巷道安全、快速掘砌且兼顾经济效益,在现场实践和室内试验的基础上,针对目前矿区巷道状况,提出钢纤维喷射混凝土支护技术,并与喷锚网和素混凝土砌碹支护进行了比较。经过理论计算和施工验证,钢纤维喷射混凝土施工进度快、巷道冒顶少、相同地质条件下每延米费用更低,在矿山施工过程中采用钢纤维喷射混凝土是合理的。
In order to achieve roadway safety, fast excavation and taking economic benefits into account, on the basis of field practice and laboratory tests, the steel fiber shotcrete support technology is proposed for the current mine roadway conditions. Compared. After theoretical calculation and construction verification, the construction progress of steel fiber shotcrete is quick, the roof of the roadway is less, and the cost per meter is lower under the same geological conditions. It is reasonable to use steel fiber shotcrete in the process of mine construction.
