Abstract: The 3201 working face of Dongfeng Coal Mine is designed with 1 767 m of reserved roadway along the track. The
overall effect of retaining roadway has achieved the expected goal, but some sections still have problems such as floor heave, wall
tilt, shear, roof subsidence, side heave and so on. After taking timely measures for maintenance, the reuse of retaining roadway
can be safely and smoothly recovered.
