Fracture evolution of the main roof in gob-side entry retaining by roof cutting of an inclined coal seam
During the application of gob-side entry retaining by roof cutting in inclined coal seams, the boundary conditions of the main roof in the goaf will change, resulting in the special characteristics of its fracture evolution. This article established a main roof elastic mechanics model through theore...
