一般认为,炸药对介质爆破的作用机理是:炸药在均匀岩石中爆炸,由爆炸中心向外依次出现压缩圈,抛掷圈、震动圈。在进行抛掷漏斗爆破时,由药包中心到自由面的最短距离称最小抵抗线W。现阶段,作为爆破设计施工的指导原则是有足够补偿空间的是根据具有自由面的最小抵抗线理论来设计的。应当充分地肯定,最小抵抗线的爆破理论,在生产上得到了广泛应用,在实践中得
It is generally believed that the mechanism of explosives on medium blasting is that explosives explode in even rocks, and compression rings, throwing circles and vibration circles appear in turn outward from the explosion center. In the cast funnel blasting, the shortest distance between the center of the pack and the free surface is the minimum resistance W At this stage, as the guiding principle of blasting design and construction, there is sufficient space for compensation is designed according to the theory of the line of least resistance with free surface. It should be fully affirmed that the blast theory of the line of least resistance has been widely used in production and has been practiced in practice
