Abstract
To improve the efficiency of cutting hard rocks in roadway tunneling, a rock breaking method using a cutter assisted with hydraulic fracturing is proposed. In addition, the influence of the circumferential distribution of holes on the crack propagation was studied through a hydraulic fracturing experiment. On this basis, an experiment of rock breaking by a cutter assisted with hydraulic fracturing was conducted, and the effect of the hydraulic...
