According to the deep well of surrounding rock to bear the vertical stress and stress levels, to the surrounding pressure, the overall convergence, serious damage to roadways, characterized by degeneration of a strong, high-stress from the deep tunnel support of the principle to start, according to the deep tunnel of the high-stress support The principle of the roadway support for the numerical simulation, generating more than support the program. Deep under the high stress of the characteristics of the roadway to determine the 5 fuzzy evaluation in order to establish a gray fuzzy model. On the roadway support program for the comprehensive evaluation of the overall design optimization. The article analyzed the high-stress conditions, failure mechanism, with the top end of drums, to help each other induced instability reasons, the development of a viable construction program. For deep high-stress conditions, roadway support and the support structure design parameters provides a reaso
