摘要
文章通过顾桥矿北一11-2胶带机下山注浆加固实例,由传统的渗透性注浆为挤压劈裂注浆,对注浆参数进行了优化,提高了巷道的承载能力,减少了变形量,保证了巷道的安全使用,为以后注浆方案设计提供了全新的借鉴典范。
North 11- 2 tape machine down mine owner thereof by Guqiao grouting reinforcement instance fracturing grouting squeezed by the the traditional permeability of grouting,grouting parameters were optimized to improve the carrying capacity of the roadway,reduce the amount of deformation,to ensure the safe use of the roadway,and learn a new for subsequent grouting program designed to provide a model.
