岩巷掘进中光面爆破参数选择

Parameter Selection of Smooth-surface Blasting for Rock Drivaging

从光面爆破的主要技术指标入手,探讨了达到理想光面爆破效果的一些参数的选取,研究了避免光面爆破超欠挖时合理炮孔密集系数的范围。

Started with the major technology quota of smooth-surface blasting, the selection method of ideal parameters was inquired into, and the reasonable hole setting which avoids the failure of smooth-surface blasting was studied.
