Planning and development of Syncrude's new truck and shovel oilsands mine

"Syncrude Canada Ltd. operates one of the largest surface mines in the world. The mining operation has two distinct phases: (1) the removal of the overburden, utilizing trucks and shovels; and (2) the mining of oilsand with drag lines and bucketwheels. Both phases combined move approximately 330 000 BCM per day.In support of current production demands and to provide a contingent oi/sand source, Syncrude has developed an Auxiliary Production System (APS) supported by the truck and shovel operation. This system utilizes oilsand sources within the existing mine area on an as-needed basis.The recent increased capabilities of the processing plant to handle a larger volume of oilsand has increased the reliance of the APS system. To facilitate the increased capacity, an auxiliary mine was developed external to the Base Mine operation with a production capacity of4.7 MBCM of oilsand per year.Development of the Northwest Auxiliary Pit began in January 1990, with the first cubic metre of oilsand taken to the plant in June, 1990. The Auxiliary Pit, as designed, has a total ore reserve of 68 MBCM of oi/sand."
