空气柱装药爆破技术能够使得周边眼爆破时孔壁承受较长时间的准静态压力作用,延长了作用时间,最终使岩壁受力均匀,减少了破碎带范围,控制了巷道成型;大幅度提高周边眼眼痕率,光爆成型效果显著,减少巷道的超挖量和喷浆量;保护了围岩完整性,增强了围岩抗压强度,再配合现有支护手段,将大大提高在深部巷道及软岩巷道中的支护效果。
Air column charge blasting technology can make the hole wall withstand the quasi-static pressure effect of the long time when the surrounding eye blasting, prolong the action time, and finally make the rock wall force evenly, reducing the range of the crushing zone and controlling the laneway forming; Improve the visibility of peripheral eye marks, the effect of light burst molding is significant, reduce the amount of roadway overbreak and shotcrete; protect the integrity of surrounding rock and enhance the compressive strength of surrounding rock, combined with the existing support means, will be greatly enhanced Support effect in deep roadway and soft rock roadway.
