Abstract
To uncover the failure and instability mechanism of coal-rock combination under loading, it is very crucial to investigate crack development and energy evolution. In this work, the uniaxial compressive and Brazilian split tests of coal-rock combinations were first performed. Secondly, the corresponding numerical models were built using the UDEC-Trigon method. Based on numerical results, the number, length and macroscopic area of cracks during...
