Abstract Influenced by collapsed coal column, fold, the recovery mining in No. 2 coal seam of Guandi Mine caused large broken surrounding rock, intense roadway section, anchor bolt and rope support failure. Bolt, cable, shotcrete joint support scheme was put forward, the technology was feasible by theoretical research, field engineering practice, late stage pressure monitoring. The study showed that the parameters were reasonable, roof separation less than 52 mm, mining roadway surrounding rock load less than 75.5 kN, the recovery mining roadway was stable, providing reference for similar roadway mining.
