Improving breaking efficiency of hard rock: Research on the mechanism of impact-shear rock breaking technology
To expedite drilling operations in hard rock of coal mines, a new type of impact-shear drill bit was developed, and its mechanism of speed-up and efficiency increase was studied. The RHT constitutive model was used to describe the structural behavior of rock, and the rock-breaking simulation model o...
