Abstract:
Taking Baijiao Coal Mine 2114 fully mechanized working face in 21 mining area of crossing mining floor main roadway engineering practice as a background, through the application of theoretical analysis and field measurement method, the paper studies roadway surrounding rock deformation characteristics, and failure mechanism, and "high-strength yielding bolt+bird-nest anchor rope+W type steel strip"roadway reinforcement scheme is applied in the field test, which solves the aforementioned technical problems.
