为了获取不同浓度的磷石膏充填料浆在管道输送过程中沿程阻力的变化趋势,采用剪切流变试验和环管试验对磷石膏充填料浆的流动性能进行研究。结果显示:磷石膏充填料浆沿程阻力随浓度的增加呈梯度增长,且浓度越高阻力增长越快。在既有充填管网和充填配比情况下,当磷石膏充填料浆管输流量低于190 m3/h时,50%~54%质量浓度的充填料浆沿程阻力变化不大,充填料浆质量浓度可提高至54%进行管道输送。鉴于充填管网的复杂性、弯头和坡度等均会导致充填管道输送总阻力损失的增加,充填系统设计须留有余量。

In order to obtain the variation trend of frictional resistance in different concentration phospho-gypsum backfill slurry,the flow performance of the slurry was studied by shear rheological experiment and loop test.The results show that the frictional resistance of phosphogypsum backfill slurry increases multistep with the increase of concentration,and the higher the concentration,the faster the resistance increases.The research results show that under the condition of existing filling pipe network and filling ratio,displacement volume is less than 190 m3/h,frictional resistance change little with concentration of 50%~54%.Therefore,backfill slurry concentration can be raised to 54% for pipeline transportation,at this point the pipeline frictional resistance is around 0.2 kPa/m.In view of the complexity of mine backfill pipeline,the total resistance of transported backfill slurry will be increased,so the design of mine backfill system should make allowances for additional resistance due to the bend pipeline and slope.
