Abstract
Methanometers with catalytic heat-of-combustion sensors used in coal mines today will read low for flammable gases when oxygen (O2) concentrations are low or when methane (CH4) concentrations are greater than 10%. Thus, these methanometers may not be reliable during operations such as fire fighting or recovery of sealed mines. The U.S. Bureau of Mines developed a total flammable gas detector (TFGD) to measure CH4 at concentrations up to 100% and to measure flammable gases in low O2 concentrations. This paper describes the operation and construction of the TFGD and discusses measurements of flammable mine gases obtained from a mine in western Pennsylvania.
