Failure Mechanism and Optimization of Arch-Bolt Composite Support for Underground Mining Tunnel
Numerical simulation tests were performed on the arch-bolt combined supported mining tunnel through an improved numerical simulation approach. The typical soft rock roadway was took as the background, and the influencing factors such as ground stress level, lateral pressure coefficient, and support...
