Formatted Abstract/Summary
Metalliferous mining operations are required to prevent contamination of the surrounding environment resulting from the discharge of leachates from waste repositories that may contain acid-forming sulfidic rocks or mine tailings. Waste rock cover systems are commonly used to isolate hazardous wastes from precipitation and thereby to prevent toxic or acidic mine drainage. Store and release cover systems are designed to retain all precipitated water within benign material overlying the waste, where the water is removed by evapotranspiration. Two cover designs were tested in semiarid monsoonal northwest Queensland: (1) 1.5 m of unconsolidated waste rock overlying 0.5 m of consolidated waste rock and (2) 2.0 m of unconsolidated benign waste rock. Cover performance was monitored with lysimeters, soil moisture and soil suction sensors. In a wet season with higher than usual precipitation (900 mm), water infiltration into underlying waste rock beneath bare covers varied from 3% to 76% of precipitation.
