A study of the hydrogeotechnical behavior of in-pit tailings and their interaction with the contact structures - Year two

Mines wastes include tailings and waste rock. Tailings are crushed rock produced by mineral extraction and waste rock is coarse material excavated to create mine openings. These wastes are commonly disposed on the surface in tailings or waste rock piles, which could pose serious environmental and geotechnical issues. Backfilling the openings of underground mines with wastes has become a common practice. The disposal of wastes in open pits is less common, yet is a promising technique. Very little research has been performed on the behavior of tailings disposed of “in-pit” and on their interaction with contact structures. In-pit disposal of mine wastes is underway at the partner’s mine. This is an opportunity to study in-pit disposal that will lead to improvements in the technique and an understanding of its effects on the environment. ponds
