摘要(Abstract):

聚能爆破技术是岩石控制爆破技术中有待开发的领域。本文介绍了该技术所用的线型聚能切割器的作用原理、设计方案及其爆破技术参数的选择;并以某水泥厂石灰石岩块控制爆破为例,采用聚能爆破技术在工程实践中取得了理想的爆破效果。该技术的开发和完善将有助于推动开挖爆破技术的发展,并会带来可观的经济效益和社会效益。
Cumulative explosion is a promising technology in controlled blasting of rock mass.The present paper discussed the action mechanism of linear cavity effect cutter,its design scheme and the blasting parameters.The technology of cumulative explosion was applied to a limestone mine with satisfactory controlled blasting effects.The application results showed that further improving and consummating the technology would result in visible economic and social profits.
