| Abstract: | According to the observation results of track along-groove roof separation in the 13501 working face of Zhujixi Mine,the influence of excavation,bolting and mesh support parameters on the stability of roadway roof surrounding rock is expounded in this paper.The field measurement results show that after the optimization of bolting and mesh support parameters,the amount of roof separation is obviously reduced,and the roadway roof is well maintained. |
