Numerical investigation of coal pillar damage mechanisms for various width-to-height ratios
Abstract Pillar stability has garnered significant attention owing to the effects of pillars on coal resource recovery rate, coal pillar stability, and coal bump risk. This study examined the roadway stability control principles of conventional and yield coal pillars. The conventional coal pillars w...
