Abstract In order to improve the surrounding rock stability of the retracement roadway and ensure the safe and rapid withdrawal of No.B10 Coal Seam working face in Shajihai Mine. By means of field measurement and theoretical analysis, the structural characteristics of surrounding rock in the retracement roadway area were studied, and the loose range of surrounding rock during severe mining was analyzed. The coupling control strategy of roof in the withdrawal space dominated by medium and long anchor cables was proposed, and the field industrial test was carried out. The results showed that the coupling control method of retractable space roof could control the shallow, middle and deep roofs, effectively reduce the deformation of surrounding rock and ensure the smooth withdrawal of working face.
