我队在井探掘进中,由于推行藥壺爆破(扩底爆破)方法,使日进尺由0.2公尺(一班作业)提高到0.5～0.6公尺,掘进效率提高2.5倍,对完成全年的井探任务起了重要作用。現將我們在推行藥壺爆破当中的具体經驗,作如下綜合介紹。
In the exploration of the wells, our team improved the daily footage from 0.2 meters (one shift) to 0.5 to 0.6 meters and improved the tunneling efficiency by 2.5 times due to the implementation of pot blasting (expanding blasting). The well exploration mission plays an important role. Now we will introduce the specific experience in the implementation of the jug blasting and make a comprehensive introduction as follows.
