| 摘 要： | 对不掏槽掘进爆破的理论研究可知 ,不掏槽掘进爆破主要降低了岩石抗爆能力 ,改变了自由面形成方向和过程 ,减小了岩石的夹制作用 ,装药爆炸后的比冲量沿炮孔更加均匀分布。因此 ,不掏槽掘进爆破从理论上优于掏槽爆破。

| Abstract: | In accordance with the theoretical study on blasting -off the solid, it mainly lowers rock's anti-blasting abilities, changes the direction and process in which free surfaces are formed, reduces rock's clamping function, and makes the distribution along the borehole of the volume of specific shock wave more even after explosives blast. Therefore, blasting-off the solid is theoretically superior to cut blasting. |
