新型等强度螺纹钢锚杆的应用研究

Research on application of new style equal strength thread steel anchor rod

论述了新型等强度螺纹钢锚杆首次工业性试验以及在应用中解决的一些关键性问题.通过在邢台矿务局东庞煤矿正式应用的现场测试,说明该新型锚杆完全满足巷道支护的要求,施工方便,安全可靠性高,与原高强度锚杆对比具有显著的经济和社会效益.

Based on data tested on site in Dongpang Coal Mine,Xingtai Coal Mining Bureau,this paper discusses new style equal strength thread steel anchor rod,which had been performed through industual testing for the first time,and how this solved some critic problems.This paper explains the new type one is in demand on gate support.This new syle bolt,compared to the old type,with the characheristics of construct convenience and high safety and reliability,will gain advanced ecomonic benefit and social efficiency.
