Optimisation and Practice of Support Parameters for Material Lane 21108 in a Mine
Taking 21 108 working face material lane of a mine in Shanxi as the research object,based on the engineering geological conditions,we put forward the joint support technology of anchor rods and ropes+reinforcing steel mesh+steel belt,and calculate the reasonableness of the technical parameters of the anchor rods'length,diameter,inter-row spacing and spacing of anchor rods,etc.The results of the engineering application show that:after the adoption of the joint programme,the top plate of the roadway,the bottom plate,and the two gangs of the left and right have small deformation and are within the deformation permissible range.This technology can effectively control the deformation and damage of the peripheral rock of the roadway.
