Controlled Burnout At an Abandoned Coal Mine Fire.
Proc 8th Underground Coal Conversion Symp Keystone Colorado 1982 Aug; :511-514
This paper presents a new Bureau of Mines technique called "burnout control" that shows promise for controlling fires in abandoned coal mines and waste banks and also for extracting the thermal energy represented by such "wasted" coals. The technique involves complete combustion of the coal in place while maintaining total control of the resulting heat and fumes. The thermal energy produced and brought to the surface as high-temperature gas can be as much as 20 times the equivalent thermal energy required to operate the burnout control system.
