| 摘 要： | 以全尾砂充填膏体为研究对象,利用四叶桨式旋转式流变仪测试质量分数为69%～81%的充填料浆的流变特征及其参数,采用赫谢尔-布尔克莱模型回归得出料浆在剪切速率为0～120 s-1条件下的流变模型.结果表明:质量分数为69%～81%的料浆流变模型为屈服伪塑性体,质量分数为81%的料浆为宾汉塑性体;流变性能指数n与料浆的质量分数呈线性关系,随质量分数的增大而增大.膏体的临界质量分数为80.91%. |
| 关 键 词： | 充填采矿法 尾砂 料浆 流变学 |

| Abstract: | The rheological characteristics and parameters of the filling slurries of 69% to 81% in mass fraction were tested with a four-bladed vane rotary rheometer taking unclassified-tailings filling paste as a research object.Based on the Herschel-Bulkley model,the rheological models were derived from regression at shear rates of 0 to 120s-1.It is shown that the rheological models exhibit yield-pseudoplastic for the filling slurries of 69% to 81% in mass fraction and Bingham plastic for the filling slurries of 81%... |
