Categorization of Factors Affecting the Resistance and Parameters Optimization of Ultra-Fine Cemented Paste Backfill Pipeline Transport

Ultra-fine cemented paste backfill (UCPB) is prepared using tailings, binder and water. The factors affecting the resistance of UCPB pipe transport are numerous complex, factor interactions restrict rational development filling design, which not conducive to reducing resistance. This paper categorizes integrates by theoretical analysis uses response surface methodology (RSM) study influence different types on results show that classified into endogenous exogenous factors. According classification, reduction rate optimized as high 25.31% 15.81%. shows categorization important for investigating flow. single-factor terms with highest significance under effect mass concentration diameter, respectively. two interaction slurry temperature, diameter flow velocity, provide new ideas reduce mine pipeline improve benefit convenience design.
