| Abstract: | 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. |
