Abstract: The background of this paper is the support of 50104 working face return airway in Caohegou coal mine. The roadway has experienced 50102 working face mining influence, and experience 50104 working face mining influence as well. The deformation of the roadway in the advance abutment pressure influence area is seriously, which has affected the movement of the coal face tail bracket, the ventilation and pedestrians. In order to reduce the mining influence and reduce the deformation of surrounding rock of roadway, Roof Cutting technology through the bidirectional energy-cavity blasting is implemented in the 50104 working face return airway. Engineering practice results show that the implementation of the two-way clustering can spin forming blasting couldt reduce 58.12% of the convergence of wall rock and 35.80% of the convergence of the roof and floor ahead of working face 10 m.
