| Abstract: | To solve the deformation of 2-559 return air roadway due to dynamic pressure influence of stoping from adjacent working face in Xinzhi Colliery, the author proposes the strong cooperative bolt-anchor support technology according to the deformation characteristics of roadway surrounding rock and the analysis of existing problems in original bolt-mesh-cable support and optimizes the support parameters, whose field monitoring data show that the proposed support optimization scheme has good control effect on surrounding rock of roadway and ensures the normal use of roadway during service. |
