摘要
眼前山铁矿实施加陡固定帮的 3并段开采方案后 ,节理发育的南帮边坡产生的楔体滑落 ,对矿山安全生产造成了较大影响。采用节理极点图、等密度图及模糊ISODATA聚类算法等分析技术 ,对南帮边坡岩体进行了合理的聚类分析 ,确定了岩体节理的优势方位 ,建立了节理倾向、倾角及迹长的概率分布函数 。
After the implementation of the combined mining scheme of three benches with steeper fixed pit wall in Yanqianshan Iron Mine, the wedge sliding of the joint-developed south slope had great effect on the production of the mine. The analysis techniques such as joint pole plot, contour plot, fuzzy ISODATA cluster algorithm were used to make rational cluster analysis of the slope rockmass. The predominant azimuth of the joint was determined and the probability distribution functions of the joint dip direction, dip angle and trace length were established, laying a basis for evaluating the stability of south slope.
