Numerical Study on Coal Burst Proneness Characteristics of Fissured Coal Mass

open access: yesLithosphere, 2022
Coal burst proneness of coal mass is a leading factor of coal burst which is influenced by fissures. In this paper, the elastic strain energy (ESE) and residual energy index (REI) were used as coal burst proneness indicators.
