coal is burned annually to generate electricity (5). Burning coal produces usable energy, but the uncon-trolled burning of coal in place creates potentially lethal hazards and degrades the environment. Although fires in activemines (6) can be catastrophic, they are usually con-trolled by the mine operator in a relatively short period.
