摘要
采用数值模拟结合现场监测方式,对玉华煤业1401薄煤层工作面辅助进风巷“三个区段”围岩变形和应力分布特征进行研究,制定出“三个区段”对应的巷道控制技术,通过现场变形监测证明了该支护技术具有良好的控制效果。
By means of numerical simulation and field monitoring,the characteristics of surrounding rock deformation and stress distribution in"three sections"of auxiliary intake roadway in 1401 thin coal seam working face of Yuhua Coal Industry were studied,and the corresponding roadway control technology of"three sections"was given.Field deformation monitoring proved that the supporting technology had good control effect.
