Mechanical model for the calculation of stress distribution on fault surface during the underground coal seam mining

The instability caused by the fault slip is one of the main factors that induce the occurrence of coal bursts. To in-depth understand the mechanisms responsible for coal bursts during the underground coal seam mining, a mechanical model used to calculate the stress distribution on fault surface and illustrate the fault slip characteristics is proposed by considering the mining-induced stress. In order to verify the validity of this model, a set...
