- W4285405279 abstract "• The dynamic properties of burst-prone coal are influenced by fissure angle. • The crack evolution behavior of burst-prone coal with single fissure is obtained. • The dissipated energy evolution of burst-prone coal with single fissure is studied. The dynamic properties of burst-prone coal are directly associated with the prevention of outburst in engineering practice. In this study, the mechanical responses and crack evolution under dynamic disturbance was investigated by considering the effect of a single prefabricated fissure. The tests were performed via the modified split Hopkinson pressure bar (SHPB) test system, an ultra-dynamic strain acquisition system and a high-speed camera system were employed. The results show that the peak load is positively correlated with the fissure angle, characterized by the increase of 1.85 to 2.3 kN with an N-shape. The main macrocracks propagated and coalesced along the end-point of fracture and loading direction, while that occurred at the middle of the fracture and parallel expanded to the loading direction under fissure angle of 90°. The main cracks are wing cracks at fissure angle of 0°, 15° and 30°, and anti-wing cracks presented under fissure angle of 45° and 60° condition. The fractal dimension increases from 1.54 to 1.67 for the decrease of fissure angle. The evolution of dissipated energy was characterized by S-shape and exhibited a four-phase pattern, the maximum value of 16 J is recorded at fissure angle of 30°and the corresponding minimum value is 11.5 J at fissure angle of 45°. The experimental results provide a reference to the prevention of coal burst in engineering practice." @default.
