Experimental study on bolt-grouting support reinforcement for crossing-seam roadway under dynamic pressure
SHEN Ming-zhu
Abstract：Aiming at the serious failure of the inclined section in crossing-seam high level gas drainage roadway during tunneling in Tashan coal mine 8104 working face, the paper studies the surrounding rock failure mechanism, and proposes a bolt-grouting support scheme, according to the theoretical study and practice, under the dynamic pressure of overhead mining in 8103 working face, the max roof-to-floor convergence is 140?57mm, the max two side convergence is102?52mm, the serious deformation of roadway has been controlled, achieving significant safety and economic benefits.
