综采工作面回撤通道变形破坏机理研究

Study on Deformation and Failure Mechanism of Withdrawing Tunnel of Fully Mechanized Coal Mining Face

以神南矿区红柳林煤矿15205工作面回撤为例,在工作面回撤期间对回撤通道的矿压数据进行现场监测,并结合数值模拟和理论分析,得出回撤通道的变形破坏机理,总结出回撤通道变形破坏的主要原因为工作面采动和周期来压。

Taking the Hongliulin 15205 working face in Shennan mining area as the case and with the field monitoring conducted on the rock pressure data of the withdrawing tunnel during the withdrawing period, combines numerical modeling and theoretical analysis to come to the deformation and failure mechanism, and come to the conclusion that the working face mining and periodic weighting are the main factors of deformation and failure of withdrawing tunnel.
