In view of the high stress composite roof supporting difficulty in F 15-23110 machine lane of Pingmei No.4 Mine, the high strength prestressed deformable pressure anchor and equalizing bird's nest anchor combined support technology according to the theory of suspension and composite beam design is applied. And the roadway surrounding rock deformation observation and the bolt drawing test is carried out. The results show that the supporting way to effectively control the deformation of roadway under high stress and composite roof, ensuring the safety mining of mining face.
