Mechanisms of Crack Initiation and Propagation in Dense Linear Multihole Directional Hydraulic Fracturing
Artificially fracturing coal-rock mass serves to form break lines therein, which is related to the distribution of cracked boreholes. For this reason, we use physical experiments and numerical simulations to study the crack initiation and propagation characteristics of dense linear multihole drillin...
