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 on-site monitoring data of the auxiliary lane of 12206 coal mine in Zhajiazai Coal Mine of Zheng Coal Group, the deformation law of the surrounding rock of the laneway along the roadway driving along the “three soft” coal seam and the variation rule of load bearing capacity of the anchor rod body are revealed, Soft “and the relationship between the actual bearing load of bolt support and the deformation of surrounding rock along the roadway driving along the soft” soft “coal seam provides theoretical basis for the optimization of bolting support parameters of roadway driving along next goaf with” three soft "coal seam.
