摘　　要：巷道锚杆轴力监测可作为判断围岩稳定性的依据。以某矿工作面辅运顺槽为研究对象,采用锚杆无损检测技术和锚杆测力计相结合的手段,获得了巷道全生命周期锚杆轴力的变化规律,结果表明:在巷道掘进初期,受巷道围岩应力重分布的影响,锚杆轴力呈上升趋势;随着巷道的不断掘进,进入稳定期后,锚杆轴力趋于稳定;在工作面采动期间,锚杆轴力再次呈上升趋势,且随着工作面的不断推进,上升趋势也逐渐明显。通过锚杆轴力的变化情况可以获取巷道围岩稳定性,以此来为巷道支护参数优化提供依据。The axial monitoring of the anchor rod can be used as a basis for judging the stability of the surrounding rock.Taking the auxiliary movement of a certain mine as the research object,the combination of anchor rod non-destructive detection technology and anchor rod measurement meter measurement has obtained the law of changes in the axis of the anchor rod of the entire life cycle of the roadway,and the results showed that,with the continuous excavation of the roadway,after entering the stability period,the axial force of the bolt tends to be stable;During the mining of the working face,the anchor axial force of the bolt showed an upward trend again,and with the continuous advancement of the working face,the upward trend was gradually obvious.The stability of the surrounding rock of the roadway can be obtained through the change of the anchor axial force of the bolt,which can provide a basis for the optimization of the roadway support parameters.
