摘　　要：基于150108轨道巷掘进期间受上覆采空区影响,巷道顶岩体破碎严重,采用传统锚杆支护效果差、锚杆支护失效率高等技术难题,瑞龙煤矿通过技术研究,决定对巷道破碎顶板施工加长预应力锚索。通过实际应用效果来看,加长预应力锚索能够在破碎围岩中形成有效支护梁结构,取得显著应用成效。Based on the technical problems such as poor effect of traditional anchor support and high failure rate of anchor support due to the overlying mining area during 150108 trackway tunneling,Rulong coal mine decided to construct lengthened prestressing anchor cable on the broken roof of the roadway through technical research.Through the practical application effect,the lengthened prestressed anchor cable can form an effective support beam structure in the fractured surrounding rock,and achieve significant application effect.
