Recording CH4 meter for underground use in coal mines

  • 19 Accesses

  • 1 Citations


A description is given of a recording instrument for the determination of CH4 in mine air for use underground. The operation of this instrument is based on the thermal conductivity principle. The range is 0–2% CH4 in air. The accuracy is better than 0.1% CH4. The apparatus is flameproof and is fed by a compressed-air dynamo whose voltage is stabilized and rectified. Compressed air is used for aspirating the mine air and as comparison gas.
