DEM simulation study on the mechanical and micro-fracture characteristics of jointed coal under direct tensile conditions

Abstract Rock burst events are frequently accompanied by the formation of extensive tensile cracks, with bedding plane dip angles fundamentally determining the tensile strength characteristics, crack propagation, and failure modes of coal measures. This study investigates the influence of bedding pl...
