ABSTRACT
Based on the in-situ reinforcing test, through the theoretical analysis and using the numerical simulating software FLAC, the stress and displacement feature of the surrounding rock in the condition of the close-range mining across over the roadway is researched and analyzed. The role of the bolt and grouting reinforcement, the interaction of the bolt and grouting and the controlling result to the deformation of the surrounding rocks are analyzed by the field test. It provides a guidance and reference for determining the reinforcing technique of the roadway and the rational layout of the working face under the condition of the similar close-range mining across over the soft rock roadway.
