Dealing with methane in mines and tunnels requires knowledge of the
circumstances under which dangerous accumulations of methane are likely to
occur. This knowledge involves the properties of the gas itself, an awareness
of where these accumulations are likely to occur, and facts on how methane
mixes safely into the mine air.
A new handbook, published by the US American National Institute for
Occupational Safety and Health (NIOSH), describes effective methods for the
control of methane gas in mines and tunnels.
It assumes the reader is familiar with mining. The first chapter covers facts
about methane important to mine safety, such as the explosibility of gas
mixtures. The second chapter covers methane sampling, which is crucial because
many methane explosions have been attributed to sampling deficiencies.
Subsequent chapters describe methane control methods for different kinds of
mines and mining equipment, primarily for U.S. coal mines.
