Abstract: In order to study the change of surrounding rock pressure arch and the design of optimal roadway support for excavation of inclined shaft under different inclinations, on the basis of Talahao Coal Mine of Dongsheng Coalfield and the Покровский layer method theory, by defining two kinds of stress paths, the internal and external boundary and arch thickness of the surrounding rock pressure arch around the straight wall arch and the circular section hole under the conditions of 6 °, 12° and 18 ° are compared and analyzed respectively. The results show that in the straight wall arch and circular cross section conditions, with the increase of the inclination angle, the distance between the upper part of the cavern and the boundary between the two sides of the pressure arch is constant and the distance of the outer boundary increases, the wall rock bearing capacity is also increased; under the three kinds of inclinations, the inner and outer boundary of the stress section of the circular section is smaller than that of the straight wall, but the main stress peak is large, which also shows that the effect of the circular arch in the inclined shaft is weaker than that of the straight wall arch shape.
