【摘要】：某铁矿采用正交实验设计和极差分析方法,研究料浆浓度、灰砂比、养护龄期三因素对充填体抗压强度的影响并进行显著性检验,并研究料浆浓度对坍落度的影响。结果表明:料浆浓度70%、灰砂比1∶6、养护龄期28d为最佳方案(成本最低),影响充填体强度的显著性因素依次为养护龄期料浆浓度灰砂比,所以矿山生产中应保证充填体具有足够的养护龄期;且料浆浓度为66%~68%时具有最佳输送流动性。
[Abstract]:The influence of slurry concentration, ash sand ratio and curing age on the compressive strength of filling body was studied by orthogonal experimental design and extreme difference analysis method, and the influence of slurry concentration on slump was studied. The results show that the concentration of slurry is 70%, the ash sand ratio is 1鈭，
