摘　　要：根据对朱仙庄矿两年来锚杆 (索 )在大跨度大断面的软岩巷道稳定性的分析 ,证明用锚杆 (索 )支护替代U型钢可缩性支架完全可行 ,而且每个交岔点可节约近 6万元 ,并有利于安全生产。According to the recent years stability analysis on bolt used in large span and large broken surface soft rock roadway in Zhuxianzhuang Coal Mine prove that it's entirely feasible to use bolt support instead of U type yielding support, furthermore,at each crossing,it can save nearly $60 000 and it's also useful for safety production.
