| Abstract: | The feed mechanism of surrounding rock and bolt supporting was studied based on the theory of elastic-plastic theory. The research shows that the support resistance has a great influence on stress and strain state of surrounding rock, by adjusting the resistance of the bolt support can change the stress state of surrounding rock and ensure security and stability of roadway. |

| Keywords: | feed mechanism of surrounding rock and bolt supporting soft coal roadway support resistance short high prestressed anchor |
