A Study of the Deformation Law of the Surrounding Rock of a Laminated Roadway Based on FLAC3D Secondary Development

To investigate and analyze the influence of different stress environments on deformation destabilization rocks surrounding laminated roadways under high stress, this study conducted numerical simulations coal–rock combination circumferential pressures highly stressed lateral pressure coefficients. In addition, a new custom constitutive structure model was constructed based Mohr–Coulomb criterion realized in FLAC3D software by combining field working conditions. The then developed for second time. results show that calculated are good agreement with experimental errors small, while differ from values two types rock pressure. is significantly smaller than customized model, which verifies reasonableness superiority self-built This provides theoretical practical bases design optimization stratigraphic roadway support underground coal mines.
