在岩土钻孔爆破中,炮孔堵塞的好坏、堵塞长度、堵塞物料的选择,对于提高炸药潜能的利用和爆破效果关系极大。炸药在介质中爆炸后,介质变形、破坏是应力波和爆轰气体联合作用的结果。炸药爆炸对介质的破坏能力,取决于炸药能量和所产生的气体体积。在钻孔爆破中,如炮孔堵塞不严或不堵塞时,炸药爆炸产生的大部分能量,将随爆轰气体的溢出造成能量的浪费。炸药的猛度越低,堵塞对爆破效果的影响越大,提高堵
In rock and soil borehole blasting, the quality of the blockage of the borehole, the length of the blockage and the choice of plugging material have a great relationship with the utilization of the explosive potential and the blasting effect. Explosion of explosives in the medium, the medium deformation, damage is the result of the combined effect of stress waves and detonation gases. The explosive damage to the media depends on the energy of the explosive and the volume of gas produced. In drilling blasting, if the blast hole is not blocked or clogged, most of the energy generated by the blasting of explosives will result in energy waste due to the overflow of the detonation gas. The lower the explosive dynamite, the greater the impact of the blockage on the blasting effect, and the higher the blockage
