在装药量为0.5～5吨和5～400吨的大爆破工艺中,包括矿块采准和崩矿时进行爆破的工艺。 1966年起,开始在地下采矿中对完善装药过程和往爆破地点运送炸药的综合机械化进行研究工作。第一阶段在塔什塔戈尔矿着手从手工作业过渡到用3-1型装药机 In the charge of 0.5 to 5 tons and 5 to 400 tons of large blasting process, including the mining block mining and blasting blasting process. Beginning in 1966, research on the mechanization of coal preparation in the underground mining process and the transport of explosives to blasting sites began.
