摘　　要：针对金山店铁矿矿体赋存条件以及回采巷道中螺纹钢锚杆支护存在易腐蚀失效的弊端而采用玻璃钢锚杆替代螺纹钢锚杆支护的现状,提出了基于加权平均法的回采巷道玻璃钢锚杆支护可行性综合评价研究方案,构建了加权平均法分析模型,确定了锚杆支护评价指标体系,并利用集值迭代法确定支护方案的权重,对比分析得到玻璃钢锚杆支护的综合价值比螺纹钢锚杆支护综合价值高,因此在矿山回采巷道中,可用玻璃钢锚杆替代螺纹钢锚杆支护。In response to the occurrence conditions of Jinhandi- an Iron ore body and the status quo of using the GFRP holt for supporting on roadway instead of the deformed Steel holt which is prone to corrosion, the paper proposes a research program for comprehensive evaluation of feasibility of the GFRP bolt support- ing on roadway based on the weighted average method by building analysis model of the weighted average method and determining the bolt support evaluation index system. The integrated support value of the GFRP bolt produced by comparative analysis using set valued iteration method to determine the weight of the suppork program is higher than one of the deformed steel bolt. Therefore, GFRP bolt can replace the deformed steel bolt supporting on roadway of metal mines.
