Investigation on the Depositing Law of Tailings Dam by Upstream Damming AITranslate
Abstract AITranslate
In view of upstream damming widely used in China metallurgical mines for tailings dam construction, description is made of the cause of tailing formation as well as its special physical and mechanical properties. Analysis is made of the effect of tailing discharge method on the depositing law of tailings dam and the dam structure as well as the effect of tailing discharge concentration/flow velocity/flow capacity/ discharge place on the formation of depositional dam. It is pointed out that during design of upstream tailing damming, the relevant factors should be fully taken into account so as to ensure a well-graded accumulation. And the proper concretion of depositional dam body within a short time is a prerequisite for a stable dam by upstream damming with tailings. The shear strength of depositional body can be improved only by proper arrangement of seepage drainage facility and accelerating dewatering concretion of the depositional body. Two examples are given.
