Abstract: This thesis focuses on the problem of high confining pressure, large deformation and incontrollability which are typical of the heavily stressed soft-rock roadway in deep ground. Based on field study, this thesis discusses the synergetic anchoring and contrilling mechanism, explores and establishes a system of synergetic anchoting technology, which integrates the technique of high pre-stress technology of bolt or cable, the technique of high anchor-hold technique of bolt or cable, the anchoring technique of linkage group, the high-strength bolted rock mass technique, the high-stiffness bolted rock mass technique, the synergetic anchoting technique of bolt or cable, and the bolt-cable-shelf anchoring support technique. It achieves an effective control of heavily stressed soft-rock roadway, results in apparent social and economic profits, and has great potentials for application and promotion.

Key words: deep roadway, heavy stress, soft rock, synergetic anchorting, synergetic effect
