The slotted support of the W4301 working face in Gaohe Mine was take as the research object, the analysis of the characteristics of the deformation and failure of the slotted working face, combined with the actual situation of the slot in the W4301 working face, a composite of “anchor net cable + ladder beam” support method was got, from the point of view of on-site support design, which can better meet the needs of on-site support, effectively control the large deformation and failure of the surrounding rock in the W4301 working face, with certain reference significance for similar roadway support.
