巷道支护是矿山巷道建设的重要组成部分,支护形式的选择对于保证巷道安全、节约材料、节约劳动量和加快成巷速度影响很大。目前,在金属矿山巷道中,占相当比例的整体混凝土支护不仅由于不能立即承受岩层压力,影响着巷道的可靠性,并且还有施工速度慢、木材消耗多、井下劳动量大、掘进工作量大和在穿过多岩层巷道时适 Roadway support is an important part of mine roadway construction. The choice of support forms has a great influence on ensuring roadway safety, saving materials, saving labor, and speeding up the formation of lanes. At present, in the metal mine roadway, a considerable proportion of the entire concrete support is not only due to the inability to immediately withstand the pressure of the rock formation, affecting the reliability of the roadway, but also the slow construction speed, the heavy consumption of wood, the large amount of downhole labor, and the amount of work required Dahe is suitable when passing through a rocky roadway
