摘要
岩石巷道浅孔爆破效果不理想,且炮眼利用率低,巷道成型差,材料损耗大。采用中深孔爆破反向光面爆破工艺,可以提高炮眼利用率和工效,提高施工的安全系数,实现了矿井高产高效。
The effect of rock tunnel shallow hole blasting is not satisfactory with the low utilization rate of porthole, tunnel poor shape, materials, great loss. Blasting back with smooth blasting technique can improve the utilization of boreholes and work efficiency, improve the construction safety factor to achieve high production and efficiency of mine.
