摘要
以山西潞安化工集团五阳煤矿南岭回风井82采区辅助运输巷某立交段为背景,针对常见11号矿用工字钢支架和现阶段U型棚支护形式进行稳定性研究,采用有限元软件(ABAQUS)进行弹性屈曲分析,通过理论计算进行了轴压稳定性分析,证明了现有U29方案相比11号矿用工字钢支架的优势,为今后软岩巷道支护工程设计提供了一定的参考。
Based on the background of an interchange section of auxiliary transportation roadway in Nanling return air shaft 82 mining area of Wuling Coal Mine of Shanxi Lu’an Chemical Group,the stability of common No.11 mine I-steel support and U-shaped shed support is studied,and the elastic buckling analysis is carried out by using finite element software (ABAQUS) and the axial compression stability analysis is carried out through theoretical calculation.It is proved that the existing U29 scheme is superior to the No.11 mine I-steel support,which provides a certain reference for the support engineering design of soft rock roadway in the future.
