| 摘 要： | 基于卧龙湖煤矿的岩石力学测试资料,运用FLAC3D数值模拟软件,分析了102工作面在回采过程中的应力重分布、覆岩的变形和破坏特征。数值模拟结果表明,随着工作面的向前推进,垂直方向应力和位移成增加的趋势,采空区中间部位岩体位移近于垂直方向。研究结果为工作面布置方法、顶板支护方式的选择和采区设计提供了依据,为顶板事故的预防提供了参考资料。

| Abstract: | Based on rock mechanical tested data from the Wolonghu coalmine,using FLAC3D numerical simulation software has analyzed stress redistribution,overburden deformation and failure features in No.102 working face during coal winning.The results of numerical simulation have demonstrated that along with working face advancing,vertical stress and displacement have a trend of increasing,rock mass displacement of central gob area near vertical.The studied result has provided a basis for working face layout method,roof support pattern selection,winning district design and a reference to roof accident prevention. |
