Abstract
Return airway of Xing Cun mine -1186 level is rock roadway penetrated strata , in the roadway through,roadway laying in the Jurassic red bed mudstone generated greater asymmetric deformation, in view of this situation, this paper presented the coupling support technology with bolt mesh anchor and corner anchor. Field monitoring results indicate that in the coupled state, the stress can transfer from the greater stress zone to the lower, stress concentration degree is reduced greatly, the surrounding rock stress ifeld is uniform, which caused the displacement ifeld to become homogenization.关键词
