Abstract: Through the study of the movement situation of the surrounding rock during the rotational adjustment oblique advancing process of working face, it shows that the deformation of roadway convergence within and beyond the outer cutting hole is more serious than normal recovery, and the two wall's convergence is bigger than the roof and floor's convergence, especially in the advancing influence violent zone of working face. The region of coal plastic zone is within the coal wall about 6 to 8 m, which is similar with the cycle pressure step. With the advancing of working face, the stress is concentrated gradually in front of the roadway. The load of advance support single hydraulic prop reach up the biggest value when old roof is fractured. The pressure can reach up 26 MPa during non-pillar connecting, and the pressure is above 10 MPa during withdrawing.
