| 摘 要： | 巷道穿层掘进时需对不同岩性区域巷道围岩稳定性进行分析,针对不同岩层情况确定合理的支护参数。随着巷道所处位置由上部向下部移动,两帮的垂直应力呈增大的趋势,巷道顶底板变形量要大于两帮。8个计算模型中,上半部分岩层区域巷道围岩变形量明显较大,在进行支护设计时,可将巷道分为两部分区别对待。

| Abstract: | It is necessary to analyze the stability of surrounding rock in different lithologic areas and determine reasonable support parameters according to different rock conditions.As the position of the roadway moves from the top to the bottom,the vertical stress of the two sides increases,and the deformation of the roof and floor of the roadway is larger than that of the two sides.In the 8 calculation models,the deformation of surrounding rock in the upper part of the rock stratum is obviously large.In the support design,the roadway can be divided into two parts. |
