Understanding roof deformation mechanics and parametric sensitivities of coal mine entries using the discrete element method
Although conventional coal mine designs are conservative regarding pillar strength, local failures such as roof-falls and pillar bursts still affect mine safety and operations. Previous studies have identified that discontinuous, layered roof materials have some self-supporting capacity. This resear...
