摘　　要：根据同煤集团南阳坡矿副斜井扩建的工程地质和开采技术条件,进行了表土段支护的初步设计,并运用数值模拟方法分析支护围岩力学状态。分析结果显示设计的支护方式能够符合现场实际,为现场顺利施工提供了依据,对同类条件下副斜井表土段支护具有指导意义。Based on the engineering geology and mining conditions of inclined vice-shaft extension of Nanyangpo Mine in Datong Coal Group Company,the preliminary support design of soil surface state was carried out,the mechanics state of support surrounding rochs was analyzed by numerical simulation method.The analysis results indicated that the designed support method can meet actual field condition,and provide basis for successful construction,and have guiding significance to inclined vice-shaft surface soil state support in similar conditions.
