Analysis of a potential coalburst phenomenon in different strata layers in underground coal mines

Coalburst is referred to as the violent failure of overstressed coal, which has been recognised as one of the most critical dynamic failures in coal mines. This paper aims to analytically and numerically evaluate the energy transformation between the different strata and coal layers. An accurate closed-form solution is developed. Due to the complexity of the causes and mechanisms contributing to the coalburst occurrence, 3D finite element...
