Permissibility Checklist for Approved Diesel Powered Coal Mining Equipment

摘要

Safe operation of diesel-powered equipment in area of underground coal mines, where methane may be present, requires the incorporation of special features to eliminate fire and explosion hazards. The diesel engine and those control devices required to reduce surface and exhaust gas temperatures to safe levels, and to prevent flames and sparks from being emitted to the mine atmosphere, are evaluated during the approval process by the Mine safety and Health Administration. The report describes the sources of the fire and explosion hazards introduced by the diesel engine, explains the permissibility checklist concept as applied to the engine and safety controls and how the concept has been expanded to include other machine related safety features.
