Coalbed gas has been considered a hazard since the early 19th
century when the first mine gas explosions occurred in the United
States in 1810 and France in 1845. In eastern Australia
methane-related mine disasters occurred late in the 19th century
with hundreds of lives lost in New South Wales, and as recently as
1995 in Queensland's Bowen Basin. Ventilation and gas drainage
technologies are now in practice. However, coalbed methane recently
is becoming more recognized as a potential source of energy; rather
than emitting this gas to the atmosphere during drainage of gassy
mines it can be captured and utilized. Both economic and
environmental concerns have sparked this impetus to capture coalbed
methane. The number of methane utilization projects has increased
in the United States in recent years as a result, to a large
extent, of development in technology in methane recovery from coal
seams. Between 1994 and 1997, the number of mines in Alabama,
Colorado, Ohio, Pennsylvania, Virginia, and West Virginia
recovering and utilizing methane increased from 1 0 to 17. The
Environmental Protection Agency estimates that close to 49 billion
cubic feet (Bet) of methane was recovered in 1996, meaning that
this amount was not released into the atmosphere. It is estimated
that in the same year total emissions of methane equaled 45. 7 Bcf.
Other coal mines are being investigated at present, many ofwhich
appear to be promising for the development of cost-effective gas
recovery.
