Research on Support Technology for Shallow Buried Soft Surrounding Rock Tunnel
Tunnel support is of great significance for the safety production of coal mines underground.Traditional anchor rod and cable support technology has poor targeting for shallow buried soft rock tunnel support and is difficult to meet the requirements of refined production in mines.The use of grouting reinforcement technology combined with reinforced concrete lining structure to support shallow soft rock tunnels enhances the strength and self stability of weak surrounding rock,improves the overall integrity and stability of the tunnel surrounding rock,and at the same time,due to the diffusion effect of grouting reinforcement,it has a certain reinforcement effect on the coal rock mass in front of the tunnel excavation,improving the safety of tunnel excavation.Practice has shown that this support technology has strong targeting for shallow soft surrounding rock tunnels.
