现行的光面爆破技术仍然存在着炸药能量利用率低的问题,并且也不能控制初始裂隙的扩展方向,所以对被保留岩体依然有相当程度的破坏。为了使光面爆破能够产生更理想的效果,科技人员在探索着一种可以控制裂隙的起始部位和扩展方向的新的爆破技术。这种技术就是断裂控制爆破。
The current smooth blasting technology still has the problem of low energy utilization rate of the explosive and can not control the expansion direction of the initial crack, so there is still considerable damage to the retained rock mass. In order to make the smooth blasting can produce better results, scientists are exploring a new blasting technology that can control the start of the crack and the direction of expansion. This technique is fracture-controlled blasting.
