Abstract: With the underground abandoned stop and ground pressure control in Dongtongyu gold mine, Shaanxi as the study case, the grooving top-caving method and the roof cutting and pillar caving method were proposed.The parameter design method for the treatment of abandoned stope was studied.As a result, a complete theoretical, practical and evaluation system for the treatment of gently inclined abandoned stope is formed, including the theoretical design, site construction and effect observation.

Key words:  Abandoned stope treatment, Grooving top-caving, Roof cutting and pillar caving, Controlled explosion
