摘　　要：本文以南阳坡矿408-2巷掘进工作面的支护为工程背景,在大断面回采巷道掘进工作面中探索使用锚杆+锚索联合支护形式。结果表明,锚杆+锚索联合支护方式巷道围岩变形过程较为平缓,围岩更快进入变形稳定阶段,能有效地保证巷道围岩稳定。Taking the support of 408-2 roadway driving face in Nanyangpo Mine as the engineering background,this paper explores the combined support form of bolt and anchor cable in the large cross-section mining roadway driving face.The results show that the deformation process of surrounding rock of roadway with bolt and cable combined support is relatively smooth,and the surrounding rock enters the stage of deformation stability faster,which can effectively guarantee the stability of surrounding rock of roadway.
