Study on the Deposition Rule of A Tailings Embankment

A combination of exploration, sampling, in-situ test, and indoor test was used to study the deposition law of tailings accumulation. The study shows that, from the top of the sedimentary beach to the direction of the reservoir, the particle size of the tailings sand gradually changes from coarse to fine, and from the beach to the downstream, the particle size of the tailings sand along the direction of the depth in general shows the law of changing from coarse to fine; the compactness of the tailings sand in general increases with the increase of the depth, and ultimately tends to be stabilized.
