Particularities of determining the economic effect from the usage of coal bed methane with various development methods of coal methane deposits

Abstract

The article is concerned with the questions of determining the economic efficiency of methane from coal bed deposits. Demands of national economy in natural gas and products of its processing dictate the need of involvement in the development of non-traditional sources of gas production, which include gas containing coal beds. All projects on extraction of methane from coal beds can be divided on two types: projects of degasification of coal mines and projects on production of methane of coal beds as a self-contained mineral deposit (commercial production). An important difference is that the industrial work with boreholes from the surface allows to extract methane-air mixture with high content of methane. At that unlike degasification the whole methane that was received during commercial production is on spec. Peculiarities of identifying the economic effect from the usage of coal bed methane, during various methods of resources development of coal-gas, additionally methodic approach to selection of one of the directions of developing of coal methane deposits are provided in the article. Additionally the article reviews historical questions of developing the coal methane processing. Main directions of processing of coal methane depending on the content of methane in methane-air mixture. Dependence on the selection of a specific option of methane usage from such economical and organizational factors as cost value on creation of processing plants on corresponding usage direction, size of economic effect from the usage of methane on this direction, organization-economic mechanism of project participants on methane extraction, specific needs of project participators in specific conversion products.
