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FLAC^3D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 goal in KT9 orebody of Shuangwang gold mine as the background, the three-dimensional models were established by FLAC3n software to study and analyze the stress and displacement distribution of surrounding rock. The results showed that there was no tensile stress in sur- rounding rock of goal. Furthermore, the compressive stress mainly concentrated on the 1~4 lines, and the most serious stress appeared on the 2 line, which led to the maximum de- formation in this area. However, the overall performance of goal was relatively stable, as well as the corresponding pillar recovery and treatment plan for goal were put forward.
