摘　　要：以某矿21108工作面材料巷为研究对象,基于工程地质条件提出锚杆索+钢筋网+钢带联合支护技术,并对锚杆长度、直径、间排距和锚索间距等技术参数的合理性进行计算。工程应用结果表明:采用该联合方案后,巷道顶板,底板,左、右两帮变形量较小且均处于变形允许范围内,该技术可有效控制巷道围岩的变形破坏。Taking 21108 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 caleculate 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 ffectively control the deformation and damage of the peripheral rock of the roadway.
