摘　　要：针对某矿1406大采高工作面回风顺槽采掘期间出现的巷道围岩变形和受到上一区段开采的动载荷影响,采用理论分析和数值模拟的方法,得出了1406回风顺槽掘进过程中的围岩应力变化规律和受采动影响下的实体煤应力分布情况,通过现场实测得出围岩变形速率和变形量,为相似工程情况提供理论依据和工程借鉴。In view of the deformation of roadway surrounding rock and the influence of dynamic load during the excavation and mining of ventilation roadway in 1406 large mining height working face of a mine,theoretical analysis and numerical simulation are utilized,the deformation of surrounding rock and the stress distribution of solid coal under the influence of dynamic pressure during the excavation of 1406 ventilation roadway are obtained,deformation rate and deformation amount of surrounding rock obtained by field measurement,which provide theoretical basis and engineering reference for similar projects.
