| 摘 要： | 目前,采用全尾砂充填脱水速度慢,且容易堵塞渗透管等不利原因,在矿山充填往往采用分级尾砂。由于分级尾砂的渗透性对脱水速度等性能有直接的影响,因此从理论分析了尾砂的级配与渗透率的关系,并通过试验得到了对矿山较为有利的尾砂级配作为充填料。

| Abstract: | Currently, due to the unclassified tailings dehydration slow, and easy to plug penetration tube, and so on, the mine are often used classification tailings. Since the permeability of tailings grading has a direct impact on the performance of the dehydration speed, analysis of the relationship between the tailings gradation and permeability, and get more favorable grading as a filling material for mine by experiments. |

| Keywords: | classed tailings the speed of dehydration tailings gradation coefficient of permeability |
