Numerical simulation of fracture patterns in roof strata with different thicknesses

Numerical simulation of fracture patterns in roof strata with different thicknesses

Abstract Roof breaking is the root cause of rock burst and mine earthquake. However, the classical “thin plate theory” and “thick plate theory” cannot fully reveal the mechanical mechanism of the influence of roof thickness-span ratio on the fracture mode. In this paper, based on the cohesive elemen...
