以双王金矿KT9矿体采空区为研究背景,通过建立采空区三维FLAC3D模型,研究分析了采空区周围岩体应力场和位移场的分布情况。结果表明:采空区周围岩体内不存在拉应力场,压应力主要集中于1~4线之间,且在2线处最为严重,导致该处岩体变形量最大,但采空区总体表现为相对稳定,据此提出了后期矿柱回采和空区处理方案。 Taking the goaf of KT9 orebody in Shuangwang gold mine as the research background, the three-dimensional FLAC3D model of goaf was established to study the distribution of stress field and displacement field of the rock mass around the goaf. The results show that there is no tensile stress field in the rock masses around the goaf. The compressive stress mainly concentrates between 1 and 4 lines, and it is the most serious at the 2nd line, resulting in the largest deformation of the rock mass. However, The performance is relatively stable, accordingly proposed post-mining pits and empty area treatment program.
