在坑道的藥室內裝置大量的炸藥,把岩石或鑛石崩碎,在採鑛学上謂之坑道爆破或硐室爆破,东北區一般露天鑛山,以其裝炸藥多,爆破量大,叫做大爆破。把鑽机的鑽孔的深孔爆破叫做中爆破,把鑿岩机打眼的淺孔爆破呌叫做炮眼爆破。多數的坑道齊發一次爆破鑛石數十万噸,但個别的單坑道爆破,爆破量不足一千噸,而多數的深孔中爆破,一次爆破也有數万噸,因此是以鑿岩及裝藥的特性區别,而不是以爆破數量的多寡來區别大爆破的。与其他各种爆破方法的比較,大爆破的優點与缺點,是比較突出的,現將其優點論述如下:
A large number of explosives are installed in the tunnel’s medicine room to crumble the rock or ore. In mining science, it is called tunnel blasting or chamber blasting. The open pit mines in the northeastern region are usually loaded with more explosives and have a large amount of blasting called " Big blast. The drilling of the deep hole blasting blasting called the blasting, rock drilling machine drilling shallow hole blasting called blasthole blasting. Most of the tunnels blow up explosively hundreds of thousands of tons of ore at a time. However, individual single-tunnel blasting methods have a blast volume of less than 1,000 tons. Most of the deep-hole explosions have tens of thousands of tons of blasting. Therefore, The difference between the characteristics of the charge, rather than the number of blasting to distinguish the number of large blasting. Compared with other kinds of blasting methods, the advantages and disadvantages of large blasting are more prominent, and the advantages are discussed as follows:
