Investigation on Cutting Blasting Efficiency of Hard Rock Tunnels under Different Charge Diameters
Considering the low efficiency of cutting blasting in hard rock mine tunnels, a novel solution of increasing the charge diameter of the cutting holes was put forward. To investigate the influence of the charge diameter on the cutting blasting results, three different working conditions of Φ 32 mm, Φ...
