摘　　要：深部条带开采影响因素很多,为研究各因素与煤柱塑性区宽度的关系,引入正交设计进行FLAC3D数值模拟方案设计。在模拟结果的基础上对各影响因素进行参数敏感性分析,同时采用Matlab软件进行线性回归分析,得出塑性区宽度与各影响因素的关系式,为深部条带开采设计提供参考。There are many influence factors in deep strip mining. In this paper, the normal design conception was introduced for the design of the numerical simulation scheme of FLAC3D in order to study the relationship of each influence factor with the plastic zone width of the coal pillar. Analysis of the parameter sensitivity of each influence factor was carried out based on the simulation results, and linear regression analysis was also made with Matlab software, finally, the relation between the plastic zone width and the influence factors was obtained, which thus provided the reference for the design of deep strip mining.
