采动条件下巷道群稳定性的相似模拟研究

Similarity simulation on the stability of roadways under mining

采用相似模拟方法,以新庄矿二水平4条暗斜井及保护煤柱为背景,研究采动过程中护巷煤柱的应力分布规律以及巷道群稳定性,探究上覆岩层的变形破坏规律及应力分布情况,以便对巷道群的稳定性进行控制。

Using similarity simulation method, the paper studies stress distribution law of protection coal pillar and the stability of roadways, analyzes the deformation rule and stress distribution of overlying strata.
