佛子冲矿采空区群模糊聚类分级及综合治理

Study on Fuzzy Cluster Classification and Comprehensive Control Countermeasures of the Goaf Group in Fozichong Mine

为对佛子冲矿104#矿体采空区群进行稳定性分级及综合处理研究,在前期空区探测的基础上,基于三维数值计算软件ANSYS与FLAC3D耦合,对采空区的稳定性进行模拟分析,选取空区顶板暴露面积及数值计算得到的采空区顶板最大主应力、最小主应力、最大位移4个因素,运用模糊聚类理论对空区进行聚类,实现采空区稳定性4分类。针对4采空区分别提出加强监测管理、加强支护、部分充填和全部充填等处治措施,以保障佛子冲矿生产安全,节约空区处理成本。

In order to study the stability classification and the comprehensive processing of goaf group in the 104# ore- body of Fozichong mine, and on the basis of earlier exploration of the goaf, simulation analysis on the stability of goaf group was made based on ANSYS and FLAC3D coupling. By selecting four factors including the exposed area of the goat＂ roof, the maximum principal stress, the minimum principal stress and the maximum displacement from numerical calculation, the goaf group are classified with the fuzzy clustering theory to realize four level classification of goat＂ stability. Aimed at these four kinds of goal, such treatment measures as strengthening monitoring and management, strengthening support, partial backfill and whole backfill were respectively proposed to ensure the production safety of Fozichong mine and save the handling cost of goaf.
