【摘要】：某鐵礦采用正交實(shí)驗(yàn)設(shè)計(jì)和極差分析方法,研究料漿濃度、灰砂比、養(yǎng)護(hù)齡期三因素對(duì)充填體抗壓強(qiáng)度的影響并進(jìn)行顯著性檢驗(yàn),并研究料漿濃度對(duì)坍落度的影響。結(jié)果表明:料漿濃度70%、灰砂比1∶6、養(yǎng)護(hù)齡期28d為最佳方案(成本最低),影響充填體強(qiáng)度的顯著性因素依次為養(yǎng)護(hù)齡期料漿濃度灰砂比,所以礦山生產(chǎn)中應(yīng)保證充填體具有足夠的養(yǎng)護(hù)齡期;且料漿濃度為66%~68%時(shí)具有最佳輸送流動(dòng)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，
