Coal pillar deformation analysis under different inclinations and spaces of structural plane

For problem that coal pillar is treated as a continuum in most of the coal pillar deformation studies without considering structural plane damage and instability in coal pillar, numerical simulation of the maximum principal stress and deformation of coal pillar under different inclinations and space...
