摘要
预裂爆破是一种常用于矿山爆破控制技术,它是一个特定的距离以及爆破的边缘布置一排预裂爆破孔,之前主要爆破钻孔爆破预裂孔,使矿山岩石爆炸,为了避免或大大减少主外预裂爆破孔表面松散岩体的破坏和作用,提高边坡的稳定性。结合息烽矿山地质、岩体特征条件,对预裂爆破技术进行了改进和应用,效果显著。
Pre-splitting blasting is a commonly used in mine blasting control technique, it is a certain distance and blasting decorate a row of pre-splitting blasting hole, the edge of a small amount of no coupling, in his hole before the main blast hole pre-splitting blasting hole, the mine rock explosion, when it reached the refractor, interference and absorption,diffusion, damage reduction greatly, in order to avoid or reduce greatly the pre-splitting blasting hole surface of loose rock destruction and effect, improve the stability of the slope. Based on the characteristics of xifeng mine geology and rock mass,the technology of pre-split blasting is improved and applied, and the effect is remarkable.
