摘要
根据许疃煤矿实际生产地质条件,通过理论分析、数值模拟、相似模拟,对受采动影响的底板上山巷道失稳力学机理、围岩应力分布、位移变形特征、塑性区演化规律进行了研究;确定了底板巷道与上部煤体边缘之间的合理水平距离(即单侧煤柱宽度);并建立了解决此类问题的研究方法。
Based on geological condition in Xutuan Mine,with theoretical analysis,numerical simulation and similarity simulation,we studied instability mechanism,surrounding rock stress distribution,displacement,and plastic zone evolution of rising floor roadway in the influence of mining.The reasonable horizontal distance between floor roadway and upper coal edge（unilateral pillar width） were determined.A research method for this problem is established.
