摘　　要：针对新城金矿尾砂输送料浆质量浓度低、输送质量不高的现状,通过尾砂沉降试验以及利用四叶桨式旋转式流变仪测试充填料浆的流变特征参数,提出了实际充填料浆输送浓度上限可以达到75%的建议。料浆质量浓度提高至75%,可以大大减少矿山用水量,有利于矿山安全生产和保护环境,社会效益和经济效益十分明显。In view of the low concentration of tailings slurry in Xincheng Gold Mine and poor transportation qualities,it is shown that the actual filling slurry concentration of transport can reach to 75%in mass in a way of the tailings settlement test and the rheological characteristics of filling slurry tested with a four-bladed vane rotary rheometer.The concentration of solution increased to 75% will greatly reduce the amount of mine water,which is conducive to the mine production safety and environmental protection,so the social and economic benefits are very obvious.
