毛主席教导我们:“在复杂的事物的发展过程中,有许多的矛盾存在,其中必有一种是主要的矛盾,由于它的存在和发展,规定或影响着其它矛盾的存在和发展。”在兴建林区公路爆破岩石中,促使爆炸起主导作用的是雷管和导火线,抓住这个关键,我们采用导火线钻孔法,提高燃烧火焰射力,保证雷管引爆。经 Chairman Mao taught us: “There are many contradictions in the development of complicated things. One of them is the major contradiction, and because of its existence and development, it stipulates or influences the existence and development of other contradictions.” In To build a forest highway blasting rocks, to promote the explosion is the leading role of the detonator and fuse, to seize this key, we use the fuse hole drilling method to improve the combustion flame fire, to ensure the detonator detonation. through
