mined-out area
    It was used in the numerical simulation of the stability of the mined-out area in a gold mine and as a result,the stress and strain distribution law was found,based on which,a scheme for the mined-out treatment and pillar extraction involving the preservation of 10 m×10 m permanent pillars with 10 m×10 m sectional area and 30 m×30 m between-pillar space was worked out.
