Sommaire: The legacy of abandoned mines in Canada creates issues that impact on both the health and safety of Canadians and the environment. Solutions to the problems of abandoned minesites require a detailed understanding of site conditions, the engineering solutions which may be relevant, and planning for effective use of the land.
In this paper, the authors outline the basic thrusts that have been developed at CANMET to address this problem. These include: multiprovincial agreements to develop a...

Sommaire: The underground mining industry has adopted significant use of mill wastes (backfill) for underground support which has often required the introduction of consolidating agents such as Portland cement or other pozzolanic agents (such as blast furnace slags) to achieve improved cohesive backfill strength. Normal Portland cement, the principal agent material used in Canada for hydraulic fill consolidation, is currently available to mines in bulk quantities at costs as much as
$150/tonne.

Sommaire: The Syncrude open pit mine, located near Fort McMurray in northeastern Alberta, produces approximately 410 000 tonnes of oil sand feed daily, which, after undergoing a bitumen extraction phase, generates approximately 315 000 tonnes of tailings solids daily. The tailings are used to hydraulically construct containment dykes and supporting beaches of the storage facilities. Tailings deposition commenced in May 1978 with the commissioning of the Mildred Lake Settling Basin which is currently...
