Victor Diamond Mine Victor Diamond Mine The Victor Diamond Mine is the first Canadian diamond mine located in Ontario, and De Beers' second diamond mine in Canada (after the Snap Lake Diamond Mine). It is located in the Northern Ontario Ring of Fire, in the James Bay Lowlands west of Attawapiskat in the remote northern part of the province. In June 2005, the Attawapiskat First Nation voted in favour (85.5%) of ratifying the Impact Benefit Agreement (IBA). Construction of the mine began in February 2006 which created 3200 positions; mining and operations will create around 400 permanent positions. The Victor Mine is an
Permafrost construction on permafrost owing to the change of soil properties of the ground on which structures are placed and the biological processes in permafrost, e.g. the preservation of organisms frozen "in situ". Building on permafrost is difficult because the heat of the building (or pipeline) can thaw the permafrost and destabilize the structure. Three common solutions include: using foundations on wood piles; building on a thick gravel pad (usually 1–2 metres/3.3–6.6 feet thick); or using anhydrous ammonia heat pipes. The Trans-Alaska Pipeline System uses heat pipes built into vertical supports to prevent the pipeline from sinking and the Qingzang railway
