Numerical modelling of strength and energy release characteristics of pillar-scale coal mass

Coal burst is a manifestation of rapid energy release, which is considered as one of the most critical operational hazards in underground coal mines. This study numerically investigates the effects of discontinuities on the strength and energy release characteristics of coal mass samples under uniaxial compression. The universal distinct element code (UDEC) was used to model pillar-scale coal mass samples that were represented by an assembly of...
