如何提高炸药能量的利用率进而控制其能量转化过程,是当前工程爆破技术的研究方向,而改变装药结构是实现这一目的的有效途径之一。近年来国内在一些工程中采用了条形药包、分集药包、不耦合装药,开始对改变装药结构的效果进行探索。苏联在一些巨型爆破工程的方案设计中,为避免大跨度峒室工程,大量采 How to improve the utilization rate of explosives energy and then control its energy conversion process is the research direction of current engineering blasting technology, and changing the charge structure is one of the effective ways to achieve this goal. In recent years, in some projects in China, strip-shaped kits, diversity kits and no-charge drugs have been used to start the exploration of the effect of changing the structure of charge. The Soviet Union in some giant blasting project design, in order to avoid large span 峒 room project, a large number of mining
