Abstract
The explosion hazard of methane-air mixture has become an increasingly serious problem in mine planning. As mining progresses to greater depths or develops in new, previously unmined areas, an advance assessment of methane gas potential can be essential for a safe and economic mine development program. The Bureau of Mines, as part of its coal mine health and safety program, has developed a simple, inexpensive test to accurately measure the methane content of coal samples obtained from exploration cores. The gas content of the coal per unit weight determined by this "direct method" test can be used as a basis for a preliminary estimate of mine ventilation requirements and to determine if degasification of the coalbed in advance of mining should be considered. The test results also can be used to estimate the methane resources of coalbeds in specific geographic areas. With the eventual decline in conventional domestic gas production and increased price of natural gas, commercial production of coalbed gas will become a reality.
