在优选适合于控爆的爆破能源以及相应改变装药结构等的基础上,缓和爆轰波峰值压力对介质的冲击作用,使爆破能量得到合理地分配与利用,称为缓冲原理。从爆破理论得知,硝酸铵炸药在固体介质质中爆炸时,爆轰波波阵面上的压力可达5～10万个大气压。这一压力首先使紧靠装药的介质受到强烈压缩,特别是在装药半径 On the basis of blasting energy which is suitable for controlling blasting and corresponding change of charge structure, the impact of the peak pressure of detonation wave on the medium is alleviated so that the blasting energy can be reasonably distributed and utilized, which is called the buffering principle. According to the blasting theory, when the ammonium nitrate explosive explodes in a solid medium, the pressure on the detonation wave front reaches 5 to 100,000 atmospheres. This pressure first compresses the charge-tight media strongly, especially at the charge radius
