Title Emergency protection of underground workers from combustion products of explosives

Bibliographic information June 1983, No.6, p.57-59. Illus. 4 ref.
Abstract Accidental burning of detonation of explosives, and sometimes even the collection in one place of a large volume of explosive, can raise the concentration of harmful substances in mine air above levels that can be handled by the normal ventilation system of the mine. It is proposed to deal with such cases with a portable bulkhead to seal off the source of the fumes. The bulkhead has a door covered by rubberised fabric strips, and an air inlet tube with a diffuser at the end. Air is supplied to the tube from the compressed air system of the mine. Equations for determining the dimensions and air requirements of the equipment are given, together with sample calculations.
