Because of the violently mining influence of 14138 working face in Zhangji mine,a supporting design is adopted to strengthen it with some simple introductions on scheme design and parameters design in geteroad of 14126 working face.Aimed at the design plan by using discrete element software UDEC4.0 to simulate the gateroad supporting effect about four kinds of working conditions under two different mining projects.The stress,displacement and plastic zone changes of the gateroad surrounding rocks are compared and analyzed from the simulation.The results show that the overall deformation is the smallest of transport gateway when it’s tunneled after the stress of surrounding rock stability in the process of mining,at the same time the results verify that the support scheme design is reasonable.
