摘　　要：用计算煤体的屈曲模态研究了开滦赵各庄矿的煤体失稳现象。该失稳模型考虑了煤体的几何非线性和弹塑性两个方面。本模型的有限元模拟结果与现场观察相一致。The instability phenomena of coal body are studied by computing bulging mode of coal body in Zhaogezhuang coal mine in Kailuan. The instability model takes into account both geometric non-linearity and elastic-plastic properties. The simulation results of the finite element method based on the model are in good agreement with the practical observation.
