Application of Bird-nest Anchor Rope and High-Strength Yielding Bolt in Cross Mining Soft Rock Roadway

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.
