摘　　要：为了保证锚喷巷道在巷道宽度较大、围岩条件较差时的稳定性,采取在顶板或拱部增加锚索加强支护的设计技术,根据普氏冒落拱理论及国家、行业现行有关标准规定,计算确定了锚索设计预拉力、轴向拉力设计值及锚索直径、长度、间排距等参数,通过现场实际应用表明,采取锚索加强支护后的锚喷巷道支护效果良好,设计方法可行。In order to ensure the stability of the bolt-shotcreting roadway when the width of the roadway was wide and the surrounding rock condition was poor,an anchors enhanced support designed technology of the roof and arch section was taken.According to Protodyakonov arch failing theory as well as the national and industrial available related standards and regulations,the designed pre-tension of the anchor,axial tension designed value as well as the diameter,the length and the spacing and row distance of anchor and other parameters were calculated and determined.The site actual application showed that after the anchor enhanced support conduced,the support effect of the mine bolt-shotcreting roadway was excellent and the design method was feasible.
