Abstract: This paper used the method of constructing a physical model and applying the Mohr-Coulomb failure theory to simulate
the appearance law of the mine pressure during the roadway tunneling process of A Coal Mine. The results show that the
mining process is the key factor affecting the shear stress, transverse stress and principal stress of the main key layer, and the
mining process is also the periodic change process of roof overhang-fracture-overhang, which can provide a basis for coal mine
safety production protection.

 Key words: coal mine roadway; mine pressure; appearance law
