The paper introduces that the cable anchor beam is combined with u shed to support the roadway roof in large embedded depth, high stress concentration area. The double support makes convergence deformation of roadway controlled within a certain range, reducing the overhaul repair quantity, and meeting the needs of the roadway ventilation and pedestrians during the mining.
