Use of filters and traps as a means to control diesel engine pollution in underground mines

Diesel-powered underground mining equipment is generally accepted as the most productive, safest, and most efficient equipment used in underground mining operations. Widespread application of this equipment to underground mining is restricted, however, largely because of the difficulty of controlling the diesel engine exhaust emissions. This paper briefly examines control devices currently available for underground application, and also discusses the theory and mechanics of controlling diesel emissions with particulate traps and filters.
