中等粒度的meso-grained
气体的形成在很大程度上取决于诸多因素、如现场实际爆轰条件、岩石类型、炮孔直径、有没有水以及炸药在炮孔中是否均匀等The gas composition is strongly dependent on many factors such as actual field detonation conditions, rock type,hole diameter,water presence,product homogeneity in the hole
水压爆破炮孔中水的等效药柱作用炸药在有水炮孔中爆炸时,冲击波经孔壁多次反射后,沿炮孔轴线方向传播的冲击波压力和所携带能量的衰减速度大大降低,波形拉宽,作用时间延长。这时可认为水的压力为准静态压力,各方面压力相等。沿炮孔轴线作用孔壁的水压力是均匀的,相当于等效药柱的作用equivalent charge column effect of water in blasthole during water pressure blasting
