摘要
为解决黑龙煤业1103工作面运输顺槽沿空留巷的支护问题,通过理论分析、数值计算等方法,确定了合理的巷旁充填体宽度、补强支护详细的参数。现场应用及巷道围岩位移、锚杆受力监测结果表明沿空巷道变形得到有效的控制,满足工作面生产的需求,为类似工作面沿空留巷的支护设计和应用提供了参考。
In order to solve the problem of retaining roadway along the gob in haulage roadway of the 1103 working face of Heilong Coal Industry,the reasonable width of filling body and detailed parameters of reinforcing support are determined by theoretical analysis and numerical calculation.Field application and monitoring results of roadway surrounding rock displacement and bolt stress show that roadway deformation along the goaf is effectively controlled to satisfy mining production requirements,which provides a reference for supporting design and application of goaf roadway in similar working face.
