What is Numerical Simulation Study on Support Design of Deep Roadway about?

## Abstract In order to solve the problem of large deformation in deep roadway mining, the stress and deformation of surrounding rock after roadway excavation and support are studied by numerical simulation. The results show that the displacement of roof and two sides is large after the roadwayexcavation. After adopting bolt support technology, the displacement of the roof and two sides of the roadway decreases obviously. The displacement decreases with the decrease of bolt spacing, the range of plastic zone decreases greatly, and the overall strength of the surrounding rock of the roadway increases obviously. The research results can provide reference for other deep roadway support.
