• Description:
  This study presents a typical stress-strain model for coal material using the available in-situ and laboratory tests data conducted on coal. This model can be used as a basic coal model in finite element applications. The effects of pillar width-to-height ratio and the confining pressure have been considered in this model. The extended Drucker-Prager model with mobilized friction angle was found to be very successful in simulating the proposed model. [Description provided by NIOSH]
