摘　　要：针对玻璃钢锚杆在高峰矿-152m平巷支护中的失效问题,运用事故树分析法从地质条件、支护方案设计、支护施工技术水平和管理水平4个方面分析了该巷道中可能导致玻璃钢锚杆支护系统失效的基本因素,并利用集值迭代法计算了各因素对系统失效的影响权重,结果表明在该巷道中锚固力大小是影响系统失效的最主要因素,爆破动载和施工规范程度也是关系到系统失效的重要因素。该研究方法对研究类似矿山巷道支护失效问题有一定借鉴意义。The basic factors which may lead to failure of the GFRP bolt supporting system in this roadway were analyzed from four aspects, including geological conditions, design of support program, supporting construction technology level and manage- ment level based on the fault tree analysis to address the failure problem of GFRP bolt in - 152 m drift supporting of Gaofeng Mine. The weight of each factor in the failure of the system was calculated using the set-valued iterative method. The result shows that the anchoring force is the most important factor af- fecting whether the system loses efficacy in the roadway. Be- sides, blasting dynamie load and extent of construction specifica- tions are also important factors related to the system failure prob- lem. The study method has a certain reference significance for roadway supporting failure problem in the similar mines.
