Numerical simulation analysis of mine pressure distribution of shallow coal seam by truncated short wall beam theory
Based on the theory of “cutting short-wall beam”,the automatic cutting-in coal-free pillar mining technology for roof-cutting pressure relief is widely used in engineering practice.However,due to the limitation of the numerical modeling of large deformation materials,the numerical simulation analysi...
