摘　　要：基于锚网钢梯 (钢带 )组合支护形式的整体作用效果 ,建立了锚杆长度和间排距之间相互依赖的关系 ,对已有的组合梁设计计算方法进行了改进 ,并在不同条件下的回采巷道锚杆支护中得到了成功的应用。On the base of integral function′s effect of the combined support of bolt and mesh ladder type of support. The mutual dependence′s relation of bolt length and the width of space and row is built. The previous combined beam′s design methods are improved. The new method has gained successfully application in actual bolting support of mining roadways with different conditions.
