An assessment of coal pillar system stability criteria based on a mechanistic evaluation of the interaction between coal pillars and the overburden
Coal pillar design has historically assigned a factor of safety (FoS) or stability factor (SF) according to their estimated strength and the assumed overburden load acting on them. Acceptable FoS values have been assigned based on past mining experience or a statistical link between FoS and probabil...
