摘要：
A novel co-disposal method, consisting of the placement of waste rock in tandem with tailings, improves the environmental and geotechnical performance of surface impoundments. The waste rock is used to create linear inclusions within the tailings. These inclusions, being more permeable and more rigid than the tailings, improve the performance in several ways, such as facilitating consolidation of the tailings and augmenting the physical stability of the impoundment. The benefits of this new concept are being evaluated by means of in situ and laboratory testing, analytical and numerical methods and monitoring at a tailings impoundment where it is being implemented.
