Abstract To address the issues of low recovery efficiency and resource waste of corner coal and triangular coal, this paper focuses on the No.15210 Face of an experimental mine. Theoretical calculations and on-site monitoring were used, the triangular coal recovery process was studied and a continuous reduction recovery plan along with corresponding chute reinforcement support measures was proposed. After field application, the surface displacement and stress distribution of roadway surrounding rock were monitored, and the results showed that the reinforcement support effect of roadway was good. The successful implementation of the continuous support reduction scheme reduced the waste of triangular coal resources and created considerable economic value.
