The Application of High Pre-stress Wire Meshes Beam and Cable Anchor Combined Support in Wufeng Coal Mine Roadway

According to the unreasonable factors of section shape and support mode in the original mining roadway of Wufeng coal mine,the paper analyzes the mechanism of deformation and failure of the roadway.On this basis,through the use of high pre-stress wire meshes beam and cable anchor combined support,the bolting(cable) space,and magnitude of installation angle and prestress are designed reasonably.The roadway section and support mode are redesigned that the support mode have been changed from passive support to active support.The deformation and failure of the surrounding rock of the roadway have been controlled effectively and the roadway safety have been ensured through the above improved scheme.
