摘要
切槽孔爆破方法具有节能显著， 爆破裂纹易于控制等优点， 但这一技术长期以来一直限于定向成缝破坏领域。本文首次提出一种三维（ 螺旋） 切槽孔爆破方法，使切槽孔爆破突破定向成缝的范围，进入松动、破碎爆破领域。
The explosion method with slotcutting hasthe merits of energy saving ,easy control of exploded cracking. However for a long time such technique was applied only in the field of directional cracking demolishing.In this paper a three dimensional (spiral) cutting slot explosion method wasfirst suggested, whichintroducessuch methodintothe field ofloosening and crushing explosion andleadsto a wider application .
