Numerical Simulation Analysis of Underground Integrated Support under High Stress

Abstract:

Using numerical simulation technology, coupling support mechanism of anchor-mesh-cable+ bottom-anchor has been analyzed. According to actual engineering of the Fifth Coal Mine of Hemei, the reasonable coupling support structure of anchor-mesh-cable+ bottom-anchor + truss under high stress has been analyzed. It is proposed roadway damage is twist deformation under high stress. By using the reasonable coupling support structure and parameter of anchor-mesh-cable+ bottom-anchor the high stress in underground rock laneway can be controlled and supporting effect is perfect.
