从载荷、矿柱结构参数和覆盖岩层等方面分析了矿柱稳定性对各影响因素的敏感程度，推导出了条形矿柱的安全系数公式。采用正交试验极差计算法得到条形矿柱对各影响因素的敏感度依次为：矿柱宽度＞矿体开采深度＞矿房宽度＞矿岩抗压强度＞上覆岩层容重＞矿柱高度。分析结果为：矿柱宽度与矿柱安全系数负相关，矿房宽度和开采深度则相反。
從載荷、礦柱結構參數和覆蓋巖層等方麵分析瞭礦柱穩定性對各影響因素的敏感程度，推導齣瞭條形礦柱的安全繫數公式。採用正交試驗極差計算法得到條形礦柱對各影響因素的敏感度依次為：礦柱寬度＞礦體開採深度＞礦房寬度＞礦巖抗壓彊度＞上覆巖層容重＞礦柱高度。分析結果為：礦柱寬度與礦柱安全繫數負相關，礦房寬度和開採深度則相反。

The sensitiveness of ore pillars stability to each influence factors is analyzed from the as-pects of load,structure parameters and rock overburden,the formula of ore pillar safety coefficient is de-duced.Based on the poor calculation method of orthogonal test,the sensitiveness of strip ore pillars to each influence factors:width of ore pillars >depth of mining >compressive strength ore-bearing rock >density of overburden bulk >height of ore pillars.The analysis results show that,width of ore pillars and safety coefficients of ore pillars are negative related with each other,while,width of ore pillars and depth of mining are positive related with other.
