摘要
以内蒙古孙家壕矿为依托,运用FLAC3D进行数值模拟,模拟了在不同侧压系数情况下,软岩巷道围岩的塑性区域和变形情况,通过分析、比较,得出侧压系数对巷道的影响规律,为煤矿安全提供一定的理论依据。
The Inner Mongolia Sunjiahao mine is studied by theoretical analysis and FLAC3Dsimulation.The plastic area and deformation condition of soft rock roadway surrounding rock under different side pressure coefficient is simulated. By analyzing and comparing, the influence rule of sidel pressure coefficient on roadway is obtained, which provides a theoretical basis for coal mine safety.
