| Abstract: | Taking extension traffic Shaft of Xieyi coal mine as the research target, the paper analyzes surrounding rock pressure appeared characteristics of the influence of the shaft and tunnel by protective coal pillar mining 4271B8 mining face. According to the observed data, it has been analyzed the deformation rule and destruction features by mining shaft and tunnel moving influence. With the help of numerical simulation, the stability characteristics of shaft and tunnel affected by cross mining in 4271B8 mining are analyzed and obtain the surrounding rock stress and plastic zone range. |
