| 摘 要： | 将采场周围含断续节理的煤岩体视为损伤介质，并考虑压剪和拉剪不同的应力环境，建立了二种应力状态下的本构关系，并将其应用于某矿采场围煤岩运移规律及破坏特征分析中。实例计算表明，所建模型能较为合理地反映现场实际，为合理计算采场矿山压力与岩层运动规律提供了依据。

| Abstract: | The constitutive relations undercompressionshearing and tension-shearing stressstates are derived regarding discontinous jointedrockmass and coal as damaged inedium and con-sidering different stress states.These relations areapplied to analyse rock movement and damage frac-ture.The caculated result agrees well with themeasured data and can be used to estimate rockmovement and stress. |
