摘要
针对巷道过含水软岩支护难的问题,根据煤岩体破碎机理,按照锚杆锚固约束层的作用原理,以及速凝膨胀水泥的特点,结合含水层围岩压力的特性,提出并试验了在含水软岩中采用速凝膨胀水泥网状锚杆支护方案,介绍了该锚杆的性能特点及施工工艺情况,解决了含水软岩快速固化的支护难题。
For the problem of difficult support tunnel in Soft rock aquifer, according to Coal and rock breaking mechanism, and the action principle of anchor stock anchoring restraint layer , the feature Quick - setting expansion cement, combining features of rock pressure, presenting adopt to cement muhihole dictyoanchor stock to soft rock aquife, introdueation to Performance characteristics and construction technology, resolvation the Supporting problem of the fast curing in water soft rock.
