摘　　要：通过动态和静态两种数值模型模拟了采区隔离煤柱应力分布规律,得出了一些有价值的结论,并按煤柱应力分布规律进行了区间划分,从而为确定煤柱留设宽度时提供了必要的理论参考。The stress distribution law of the isolated coal pillar in coal mining district was simulated with dynamic and static digital models. A valuable conclusion was obtained from the simulation. Area classification was made according to the stress distribution law of the coal pillar. All above have provided the necessary theoretical references to the width of the coal pillars setting.
