“三软”煤层沿空掘巷锚网支护承载性能分析

Study on Carrying Capacity of Bolt Support in “Three-soft” Coal Seam Roadway Drifting along Goaf

根据郑煤集团赵家寨煤矿12206下副巷现场监测资料,分析"三软"煤层沿空掘巷过程中巷道围岩的变形规律和锚杆杆体承受载荷的变化规律,揭示"三软"煤层沿空掘巷时锚杆支护实际承受载荷与围岩变形的关系,为"三软"煤层沿空掘巷锚网支护参数优化提供理论依据。

According to the monitoring data deformation laws of surrounding rock and the in 12206 roadway in Zhaojiazhai mine,analyzing the carrying capacity of bolt support in ＂three-soft＂ coal seam roadway drifting along goal, and revealing the relationship between them,providing theory basis for the parameter optimization of bolt support in three-soft coal seam roadway drifting along goaf.
