Title Environmental aspects of auxiliary ventilation
Bibliographic information Oct. 1981, Vol.141, No.241, p.217-226. Illus. 25 ref.
Abstract A short review of basic ventilation systems for headings or tunnels is followed by description of ventilation systems suitable to deal with the main environmental problems in underground workings: shotfiring fumes, firedamp, and heat. Aspects of dust control in mechanised drivages using controlled recirculation systems of auxiliary ventilation are discussed. Sources of firedamp and heat in headings are considerd. Heat from various sources (geothermal heat, heading machines, auxiliary fans) is evaluated quantitatively. Discussion about: heat released by caving rock versus monolithic packing; methane concentration and recirculation system; dust sampling technique; heat resulting from the oxidation of coal; heat from autocompression of air.
