摘要
Abstract
Aimed at improving mine roadway repair in fault fracture zone,this paper,building on grouting reinforcement theory and the experiments of grouting material ratio,presents an analysis of the relation between the geling time and cement-water-glass in different volume ratio conditions,and an analysis of the relation between the compressive strength and cement-water-glass in different volume ratio conditions.The paper features the best volume ratio of cement-water glass of 1:0.4 for grouting reinforcement,offers the mine roadway repair scheme tailored to the grouting reinforcement by combining U-shaped shed with shotcrete according to the practical conditions,and provides a better solution to on-site problems.The research has reference to repairing similar mine roadway with fault fracture zones.关键词
