| Abstract: | The 2102 belt tunnel in Dongzhouyao Coal Mine is taken as the engineering background.The high prestressed strong bolt support theory is used to optimize the tunnel support.The combined support technology of strong bolt and anchor cable is used to increase the bearing capacity around the surrounding rock of the newly excavated tunnel.The results show that the optimization of roadway support plays an important role in strengthening the support,ensuring the safety and stability of the 2102 tunnel during driving and working face mining under the intrusion of lamprophyre. |
