通过现场实测获得了白坪煤业三软煤层回采巷道变形破坏特征规律,采用极限平衡拱理论,分析确定了三软回采巷道锚网(索)+U型棚支护参数。经过现场试验,表明该支护方案能有效控制三软煤层围岩巷道变形。
通過現場實測穫得瞭白坪煤業三軟煤層迴採巷道變形破壞特徵規律,採用極限平衡拱理論,分析確定瞭三軟迴採巷道錨網(索)+U型棚支護參數。經過現場試驗,錶明該支護方案能有效控製三軟煤層圍巖巷道變形。

According to the analysis of the test in Baiping Coal Mine, the author obtained characteristics of deform-ation and failure in three soft seam roadways. The paper uses the theory of limit equilibrium arch analysis and deter-mines the support parameters of bolt ( cable ) +U shed in three-soft seam roadway. On-site testing shows that u-sing this support scheme can efficiently control the surrounding rock deformation in three-soft seam roadway.
