Research on Optimal Proportion of Cemented Filling Materials and its Strength Forecasting

9th International Symposium on Mining with Backfill
Dongsheng Xu,
Abstract There is sort of uncertain correlation between the strength of cemented filling materials and the proportion of its components such as coal ash, cement, lime and sand, etc. which may be disturbed by random errors. Based on massive experimental results, the author established a multiple linear regressive model with help of the software Matlab. The model can help to figure out the correlation between the random variables and the controlled variables using experimental results, which is the theoretical basis to the optimal proportion of cemented filling materials, the strength of the back filling body can be predicted as well.
