摘    要:通过对在顶板不坚硬、有动压复合顶板巷道中使用金属树脂锚杆、钢带、喷浆联合支护机理的分析,指出了传统棚式支护被动承压、断面利用率低以及维修量大的缺点,提出了加强爆破控制对支护施工质量的影响因素,探讨了锚杆、钢带、喷浆作用范围。

关 键 词:巷道  联合支护  锚杆  爆破

Authors:WANG Xiang-yu
Abstract:Through analyzing the mechanism of combined support with metal resin bolt,strip,shotcrete in the no-hard roof and dynamic pressure compound roof,the shortages of passive pressure,low utilization rate and large maintenance amount in the traditional shelf-supporting are pointed out.The influence factors on the construction quality with strengthening the blasting control are proposed.The effect range of anchor,strip and shotcrete is discussed.
Keywords:tunnel  combined support  bolt  blasting
