Research on the Control Technology of Dynamic Pressure Tunnel Perimeter Rock in Full-Mechanized Caving Mining
In order to realize the effective control of the deformation of surrounding rock in the dynamic pressure roadway,taking 3603 transportation tunnel as the research object,it is proposed to control the deformation of surrounding rock in the transportation tunnel by truss anchor cable,anchor rods,monolithic and grouting.After the application of the project,it solved the problems of large deformation of perimeter rock and failure of some anchor rods(ropes)in 3603 transportation tunnels under the influence of 3601 working face mining,and the amount of top and bottom plates and the two gangs moving close to each other was controlled within 170 mm and 240 mm,which achieved a better effect of deformation control of perimeter rock of the tunnel under the influence of dynamic pressure.
