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。 According to the engineering geology and mining technical conditions for the extension of the auxiliary shaft of Nanyangpo Coal Mine in Tongmei Group, the preliminary design of topsoil support was carried out. The mechanical behavior of surrounding rock was analyzed by numerical simulation method. The analysis results show that the designed support method can be in line with the actual situation in the field and provide a basis for the smooth construction on site, which is of guiding significance to the support of the topsoil section of the secondary inclined shaft under the same conditions.
