Rheological Properties of Filling Slurry in Pipeline Transportation for the Total Tailings Angang Mine
摘要
Abstract
Based on the principle of Bingham fluids hydrodynamics, tests with gravity filling slurry flow of Angang Mine through an L-shaped pipe were carried out, so as to study the rheological properties of filling slurry and the pipeline transportation ability. The experiments measured the rheological properties of filling slurry with cement-to-sand ratio of 1:6, 1:8, 1:10 and the concentration of 66%, 68%, 70%, and 72%. The results indicated that cement-to-sand ratio and concentration have greater influence on the yield stress, viscosity coefficient and the pipeline resistance than concentration. The better parameter for the Angang Mine is concentration 70%, binder consumption is 11%, stowing gradient 3.29 at most and pipeline resistance 7.02kPa/m. the research results not only provide basis for the design for filling system of Angang Mine, but also provide a reference for other Mine which has similar circumstances.关键词
