摘　　要：赤泥与尾矿不同,其粘性强,碾压密实后渗透性弱,物理力学性质较好,因此对于排放方式的选择也有更多的余地。采用何种排放方式,应根据场区地形、氧化铝厂位置等多方面因素确定。以某氧化铝项目赤泥堆场为例,对赤泥库前排放和库尾排放方式进行了场地布置、基本参数、建设费用、优缺点等方面的综合比较。对于狭长的山谷型滤饼干法赤泥堆场,采用库尾排放的方式堆存,更具有经济效益,运行管理也更为方便。Unlike tailings,red mud has strong viscosity,weak perm eability after compacting,and better physical and mechanical properties,so there are more choices of discharge methods.What kind of method to use should be determined according to the topography of the site,the location of the alumina plant and so on.Taking the red mud disposal site of an alumina project as an example.A comprehensive comparison between the discharge modes of the red mud from the front-pond and the end-pond were analyzed.For the dry red mud stack of filter cake in long and narrow valley,it is more economical and convenient to discharge from the end-yard.
