The Viability of Using the Mixtures of Mine Tailings and Waste Rock in Water Balance Covers
The focus of this study was to evaluate hydrologic performance of mixed mine tailings and waste rock in water balance cover systems via one-dimensional numerical modeling. Comparisons were developed between an actual water balance cover and the following theoretical scenarios: (1) cover systems with storage layers composed of (i) copper, (ii) gold, (iii) coal, and (iv) oil sand tailings; (2) constant thickness mine tailings storage layers with waste rock inclusions; and (3) re-designed storage layer thickness composed of tailings and waste rock to yield comparable percolation rate to covers with no waste rock. Percolation rates ranged between 0.0 and 3.2 mm/yr for pure tailings water balance covers, which was comparable to predictions for the actual earthen cover. Addition of waste rock increased percolation in all cases due to reduced storage capacity. Re-designed covers composed of tailings and waste rock yielded thicker storage layers, but comparable percolation rates to water balance covers with no waste rock inclusions.
