Present Status and Outlook of Coal Bed Methane Industrial Development in Coal Mine Area

The paper summarized the present status of the coal bed methane drainage, extraction and utilization and the progress of the clean development mecha nism project in China coal mine in recent years.Due to the geological condition of the coal bed methane in China was complicated in the plate tectonics, the coal structu re was seriously destroyed and the permeability was commonly low, the non-homogeneity of the deposit was strong, the high rank and low rank coal were taking the ma in position and other specialty, thus the coal bed methane industrial development in China shall be along the road of the coal bed methane and coal coordinative develo pment.In addition, the coal bed methane resources development and utilization policy in combination with the coal bed methane surface development and the undergro und mine drainage should be implemented.In comparison with the USA, over 70% of the coalfields in China would not be suitable to have a large scale coal bed methan e development at surface, but in according to the underground mining project schedule, the surface and underground mine combination, the surface pre-mining, underg round mining and underground drainage multi modes could be applied for the coal bed methane development.Finally the paper analyzed the advantages and faced diffif culties in comparison with the coal bed methane development and the surface coal bed methane development in China coal mines and pointed out the coal bed methan e industralization progress of the coal mine would be speeded up under the promotion of the national encouraging policies, with the key technology development and d emo project verification and promotion of the state science and technology important projects.
