Study on stress characteristics of deep roadway bolt based on nonlinear dilatancy angle model
Full-length bonded bolts are widely used in deep mining engineering and an in-depth understanding of their mechanical characteristics under complex and high ground stress conditions is of great significance for deep roadway support systems. Based on a quantitative GSI rating system of surrounding ro...
