Longwall Ignition Suppression.
NTIS: PB/270-696 Available for Reference At Bureau Libraries :146 pages
The results of a study of longwall ignition hazards and specific suppression systems to minimize each of the major hazards is described. Three classes of potential ignition suppression systems are discussed: triggered suppression systems for face ignition, passive suppression systems, and control of ignition hazard in the gob. The triggered suppression systems include protection for the shearer, head and tail gates, welding equipment, and the shearer power cable. Passive systems include improved ventilation and water sprays and charges in the shearer head. Gob protection can be improved by isolating the gob from working areas and by introducing inerting agents into the gob.
