The new coal camps had much better housing and facilities than the older coal camps.

The mine began production on September 11, 1997, and produces an average of 1,660 tons of coal daily from one super section utilizing two mechanized-mining units (MMU) and is ventilated with two splits of air. Coal is transported from the super section to the surface via belt conveyors. The immediate roof is comprised of shale and sandstone.

A mine mouth electric plant is a coal burning electricity generating plant that is built close to a coal mine. In these plants, coal is excavated from the dig site, placed on a conveyor belt, and run directly into the plant where the coal will be burned. In western Canada, the main coal mines include Boundary Dam, Paintearth, Poplar River, Highvale, and Sheerness mines—which are all mine ...
