冶金系统露天矿梯段深孔爆破技术,在科研、设计、高教‘i生产单位的互相协作下,近年来有r较大的发展。大区多排孔微差爆破、留渣挤压爆铲、小。i抗绂宽孔距爆破、预裂和缓冲爆破等碍到了广泛’彭用,并在孔网参数、布孔方式、装药结构、磐填比例、炸药鸥岩性17亡一已、微差咄j隔时间、起爆顺序和合理留渣厚度等的优化方面进行了综合研穷,取得了显著
In the open pit mine metallurgy system deep hole blasting technology, in scientific research, design, higher education ’i production units of mutual cooperation, in recent years there is a greater development. Multi-row holes in the region blasting badly, leaving slag squeeze blasting shovel, small. i anti-绂 wide-borehole blasting, pre-cracking and bursting blast to a wide range of ’Peng with, and in the hole network parameters, the way the hole, the charge structure, In the meantime, the optimization of detonation sequence and reasonable residue thickness has been comprehensively studied and achieved remarkable results
