Abstract: Mine enterprises widely use the technology of bolting(cable)support to control the stability of roadway roof and surrounding rock.However, due to the difference of geological environment and stress conditions, the design and implementation of soft rock roadway support technology is relatively difficult, which results in the poor environment of soft rock roadway support.Aiming at the serious fracture of the roof and two sides of the 9107 working face soft rock roadway in Longmenta mine, this paper designs and applies the supporting parameters of the soft rock roadway by combining theoretical analysis with field practice and adopting the combined support scheme of “anchor rod+anchor cable+metal mesh”.The actual monitoring results show that the maximum subsidence of the roof is 96 mm and the maximum displacement of the two sides is 135 mm, which effectively controls the deformation of the surrounding rock of roadway with good overall supporting effect.
