In Situ Tests Comparing the Support Effects of Thin Spray-on Liner and Shotcrete on a Roadway Subjected to Blasting
Shotcrete has been widely used in the support of tunnels and mine roadways, but frequent blasting disturbances can easily cause it to spall from rock surfaces. In previous laboratory tests, it has been shown t...

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...

Open AccessOptimization of the matching relationship between the stemming length and minimum burden in cut blasting of large-diameter long-hole stopes
Cut blasting, in which new surfaces and relief space for subsequent blasting are created, is one of the most critical steps in the establishment of large-diameter long-hole (LDL) stopes. To reduce the damage t...
