摘　　要：充填采矿法广泛应用于深部矿产资源的开发过程中,而充填系统作为充填法开采的重要组成部分,是由许多子系统构成的复杂系统,其稳定性影响因素具有模糊性和随机性。本文引用层次分析法,从原料供给系统、浆体制备系统、浆体输送系统、采区系统及其他因素这5个方面对其影响因素进行定量分析。结果表明,防管道磨损技术、防堵爆管方式、充填料浆配合比、减压方式、充填料浆浓度、充填料浆坍落度、胶凝剂等对充填系统稳定性的影响最大。Filling method is widely used in the deep process of development of mineral resources. As an important component of filling mining method, filling system stability with fuzzy and stochastic influencing factors, is a complex system which consists of many sub- systems. In this study AHP is introduced, and influencing factors are quantitatively analyzed from five aspects of raw materials, slurry preparation system, slurry delivery system, mining areas and other factors. The results show that pipeline anti-wear technology, the anti- burst pipe way, filling slurry mix ratio, decompression means, filling slurry concentration, slurry filling slump, gelling agent have the greatest impacts on the stability of filling system. The results provide a scientific and reasonable theoretical basis for the design of filling system used in the mine production.
