In order to effectively control the harmful deformation of the surrounding rock and achieve the safety of the working face during through the abandoned roadway area, based on the problem of abandoned roof caving surrounding rock fragmentation and other issues in Huanglian Mine 3300 fully mechanized caving face, theoretical analysis, numerical simulation and industrial test were applied to study the problem of abandoned roadway surrounding rock controlling, pier column filling technology was put forward with field application. The results showed that using pier column filling technology could support the roof and effectively control the rock deformation, which ensured the safe, efficient and fast mining in the abandoned roadway. Pier column filling had the absolute economic advantage when compared with the hydraulic pillar supporting.
