<p>To study the crack propagation characteristics of the V-shaped energy- accumulating charge at different angles, a new numerical laser caustics test system was used to observe the fracture process of the V-shaped energy-concentrating charge; the mechanical distribution mechanism around the blast hole of the energy-accumulating charge was analyzed, and fractal theory was used to evaluate the damage degree of the energy-accumulating charge. A series of caustics test results show that the main crack has a longer expansion length in the energy-concentrating direction, and the crack expansion length is shorter in the nonenergy-concentrating direction. The fractal damage results of the energy gathering perforating charge indicate that as the angle of the charge increases, the damage caused by energy gathering blasting gradually increases, the complexity of crack propagation increases, and the main crack follows the direction of energy accumulation. The directivity becomes increasingly less obvious. When the energy gathering angle is 120°, the main crack propagation process is similar to that of the circular charge (control group). The shaped charge can be used for directional fracture control blasting, which helps to control the direction and number of cracks and improve the blasting effect.</p>
