Compassion experiments of tailings were carried out with a self-made deep cone model,and the compaction effects were investigated under the conditions of dynamic compaction and static compaction.When the rotational speed is 0.05 to 0.80 r·min~(-1),the limit mass fraction of tailings is in the range of 67.41%to 70.73%;under the same conditions,it is only 55.82%for static compaction.Dynamic compaction has a higher compaction because excess water can move up through the water-guiding rod,but static compaction mainly relies on the gravity.The extrusion process of tailings can be simulated by theoretical extrusion models:the static compaction behavior corresponds to a simple spatial structure,while a cone structure for the dynamic compaction behavior.The theoretical value of unit sedimentation height calculated by the two kinds of models is 29.32%,and the test result is 28.81%,0.51%lower than the theoretical value.
