1950年内,我们对凿岩爆破方式上的研究和改良方面得到了一些成绩,并曾试用了或创造了许多的形式。虽然我们曾经注重地提倡了直线式(即龟裂式)凿岩爆破法,但它尚没有普遍地为各矿推广或坚持实行,这说明了我们在凿岩工作上还没有摸到一条最合理的科学方法,同时也说明了我们对于直线式爆破法还缺乏认真的研究与坚持实行的精神,因此,不是遇难而止,就是强调条件赶不上而停止了“最近我们看到了“苏联金属矿山爆破工作”一文,文中对于直线型凿岩方法做了斩钉截铁的结论。它说:“在高与宽度不到1.8×1.5掌子内,不管坑道方面怎样,采用直线式炮眼是最合适的。……所有的矿山及研究机关的实际经验
In 1950, we got some achievements in the research and improvement of the rock blasting method, and we have tried or created many forms. Although we have once advocated the straight-line (ie, cracked) rock-blasting method, it has not yet been widely promoted or implemented in various mines, which shows that we have not yet got the most reasonable drilling operation Scientific method, but also shows that we still lack of serious research and practice of the spirit of straight-line blasting, therefore, is not only killed, that is, stressed the conditions can not catch up and stopped “Recently we saw” the Soviet Union’s metal mines blasting work “Article, the article on the straight-line rock drilling method to make a definite conclusion.It said:” In the height and width of less than 1.8 × 1.5 in the palm, regardless of the tunnel aspect, the use of linear borehole is the most appropriate. ... all the practical experience of mines and research institutes
