矿井巷道支护加固中注浆技术的应用

在矿山生产与建设的过程中,巷道稳定性控制是一项难题,特别是具有集中的断层破碎带,同时在很大程度上受到构造应力的影响时,很容易导致巷道失稳,造成整条巷道垮落冒顶甚至报废。采用注浆加固技术通过巷道冒落区,能很好地解决巷道施工中的冒顶问题,加快施工进度,解决矿山掘进中的施工安全问题。

Application of Grouting Technology in Mine Roadway Support and Reinforcement

In the process of mine production and construction,tunnel stability control is a challenge,especially fault and fracture zone which has the character with concentration,and meanwhile,influenced by the tectonic stress in a large part,which is easy to lead to tunnel instability,brings about caving and roof fall of the whole tunnel,even causes scrap.Adopting grouting reinforcement technology passing caving area can solve the problems of roof fall in the construction of tunnel,speed up the construction progress...
