从许多文献资料来看,炮眼采用水封,是最有效的爆破防尘手段。采矿工业中采用水封爆破防尘不是新的问题。在有色冶金矿山和采煤工业中进行的一系列工业试验证明,这种防尘方法效果较好。可以肯定,在工作面炮眼采用水封爆破,再加上通风,可以使空气迅速得到有效 From many literature, the use of water seal hole, is the most effective means of blasting dust. It is not a new problem to adopt dustproof blasting dust in the mining industry. A series of industrial tests conducted in the non-ferrous metallurgy and coal mining industries have proved that this dust-proof method works better. To be sure, the use of water blast in the face blasthole explosion, coupled with ventilation, can make the air quickly and effectively
