Washington state's Centralia mine produces 4,800,000 tons of low-sulphur coal annually. The entire output is used for power generation. The geology and exploration of the mine are described. The equipment used for overburden removal, surface mining and trucks used for mine haulage are specified. The coal preparation plant, including waste disposal and treatment of waste water, is described briefly. Land reclamation is practiced with initial revegetation of annual grasses; wheat is grown afterwards; and, for the long term, reforestation with Red Alder and Douglas Fir is planned. (LTN)
