摘要
综合考虑多种影响充填体强度的因素,利用多元线性回归原理和方法进行统计分析,根据正交试验数据,建立了充填体强度与干料质量百分含量Cw、水泥含量、水灰比的多元线性回归方程经验模型,并对此模型进行了F、R和t值显著性检验。建立起的模型适用性较强,F、R、t值的显著性检验均能够较好地通过,方程性质能够较好地与试验过程中观察和实测到的规律和数据相吻合,因此可在生产实践当中作为一种参考和借鉴,用来指导分级尾砂充填采矿实践。
Many factors affecting the strength of backfilling were considered synthetically and the statistical analysis was made by means of the principle and method of the multivariate linear regression.According to the orthogonal test data,the empirical model of multivariate linear regression for the strength of backfilling related to its slurry s concentration,cement content,ratio of water and cement was set up and then,the significances of F、R、t were tested.The model has better applicability and the character of ...
