Abstract: 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.

Key words: Drill holes for filling, Abrasion factor, Analytical hierarchy process
