Burden Effects on Rock Fragmentation and Damage, and Stress Wave Attenuation in Cut Blasting of Large-Diameter Long-Hole Stopes
Cut blasting with single free surface is the first step of the large-diameter long-hole (LDL) mining method, which creates more relief space for subsequent blasting procedures. The minimum burden (W) is a critica...
