영문 초록

Coal is both source rock and reservoir rock for the coalbed gas. Coalbed gas. Coalbed gas is predominantly methane and has a heating value of approximatly 1000 BTU/ft\sup 3\. Most of methane is stored in the coal as a monomolecular layer adsorbed on the internal surface of the coal matrix. The amount of methane stored in coal is related to the rank and the depth of the coal. THe higher the coal rank and the deeper the coal seam is presently buried, the greater its capacity to hold gas. Most of Korean Coal is anthracite or metaanthracite, Ro. 3.5~5.5%, and total reserves are 1.6 billion metric tons. The domestic demand for coal was drastically decreased and the rationalization policy carried out from 1987 on coal industry. Now that a large number of coal mines was closed only a few mines continued to produce not more than 5 million tons for year. It is therefore recommended to formulate a strategy to explore and exploit the resources of coalbed methane in Korea.
