Mining & Minerals

DESCRIPTION

Mining and mineral processing may generate methane and combustible coal, graphite or metal dust. Dust areas may be classified as Zone 20, 21 or 22 under IEC/ATEX, or Class II, Division 1 or 2 under NEC. Underground mines may require Group I equipment for firedamp hazards. Equipment must match the substance, temperature limits and site conditions.

REPRESENTATIVE HAZARDOUS ATMOSPHERES

  • Methane (firedamp)
  • Coal dust
  • Graphite dust
  • Combustible metal dust
  • Flammable process vapours

TYPICAL APPLICATION LOCATIONS

  • Underground mine workings
  • Crushing and screening areas
  • Conveyor transfer points
  • Ore processing facilities
  • Coal handling and storage areas
  • Dust collection systems
