Current Status of the Research on Coal Geology in China

Coal is the main energy in China, which has already played and will continue to play an important role in the national economy. Coal geology, as a practical science, has an access to gradual development with the growth and prosperity of China. From the meaning of the coalfield geology, this paper introduces the research progress and status of coalfield geology, including the research on coal basin, stratigraphy of coal-bearing stratigraphic sequences, coal-forming process, structural geology of coalfields, and exploration and development status of coal resources. The paper specially focuses on coal-forming process, including coal formation in terrestrial facies and transgressive / regression events, and introduces new technology which has been applied to research progress in structural geology of coalfield. This paper puts forward a new comprehensive exploration system for coal exploration and reviews regional coal geological exploration results in recent years, such as coal-poor regions of seven provinces in southern China and the coal resources area in northwest China, which will be an important coal-producing area in the future .
