摘　　要：分析了某矿1209材巷围岩大变形特征,提出采用多维预应力锚索桁架进行控制;研究了维预应力锚索桁架主要优势和作用原理,并在现场进行了应用实践,现场监测得出采用多维预应力锚索桁架进行控制后巷道围岩顶板和两帮变形量显著降低,保障了巷道围岩的稳定性,取得了良好的应用效果。Based on the analysis of the large deformation characteristics of the surrounding rock of 1209 material roadway in a mine,a multi-dimensional prestressed anchor cable truss is proposed to control the deformation.The main advantages and working principles of the multi-dimensional prestressed anchor cable truss are studied and applied in the field.The field monitoring shows that the deformation of the roof and two sides of the roadway surrounding rock is significantly reduced after the multi-dimensional prestressed anchor cable truss is used to control,which ensures the stability of the roadway surrounding rock and achieves good application results.
