摘　　要：充填钻孔系统是一个复杂的系统,其影响因素具有随机性和模糊性。分析了充填钻孔的主要磨损因素,引入层次定量化分析方法,对金川公司充填钻孔磨损因素进行了定量化分析。结果表明,偏斜率是影响钻孔使用寿命的主要因素,其所占的权重为35.3%;其次为内衬材质和施工质量,所占的权重分别为9.8%和9.4%。这为钻孔的使用和科学决策管理提供了有力的理论依据。The system of drill-holes for filliong is complex and its influence factors are random and fuzzy. The main abrasion factors of drill holes for filling are analyzed and AHP quantitative method is adopted for Jinchuan Company＇s case. The results indicate that the slew rate is the main factor influencing the drill hole life ,which has a weight of 35.3% , and the next factors are the lining quality and construction quality,with their weight being 9.8% and 9.4% respectively, hereby providing the powerful theoretical basis for the drill hole utilization and a scientific policy decision management.
