摘要
从研究长锚索锚体结构和锚固方法入手,提出螺旋体长锚索注浆加固技术在特定条件下的应用,现场实践证明,在采场矿岩节理发育,上盘围岩不稳固时,采用长锚索注浆加固技术具有简单可靠、安全高效的特点。
Starting with the study of long rope bolt structure and anchorage method,it is put forward that groutingreinforcement with long screw rope bolt is applied in special conditions. Site practice proved that grouting reinfo-rcement with long rope bolt technique is simple, reliable, safe and high efficiency under developed mine rock andunstable hanging rock.
