metals in coal and coal-bearing strata impacts of coal mining and acid-mine drainage by and end products of coal utilization related to geology and constituents of coal emission reduction and carbon capture and storage geological aspects of coal fires and underground coal gasification Relative to coal, natural gas has less of a CO 2 'footprint'. Thus, methane extraction from coal has several benefits, some of them more obvious than others. A new paper headed by Prof Yong Qin* (China University of Mining and Technology, Xuzhou) has just been published which reviews the coalbed methane (CBM) resources in China.

These variations will yield different types of coal. Illustration by the West ia Geological and Economic Survey.

The methods used to extract coal depend on the geology of the coal deposits. According to Energy Trends Insider, the amount of coal produced by one miner in one hour has more than tripled since 1978 because of improvements in mining technology and the growth in surface mining. The majority of the world's coal is mined from China, the United

China Coal Mining is one of the world's largest exhibitions of products and services for the coal, mining and related engineering industries. The goal is to bring in new exhibits including non-coal mining, energy and new energy equipment. A series of technical seminars will be hosted to facilitate dialogue among members from the mining industry.

The geology of China (or the geological structure of the People's Republic of China) consists of three Precambrian cratons surrounded by a number of orogenic belts.The modern tectonic environment is dominated by the continued collision of India with the rest of Asia starting 40–50 million years ago. This has formed the Himalaya and continues to deform most of China.

China has large but uncertain coal mine methane (CMM) emissions. Inverse modeling (top-down) analyses of atmospheric methane observations can help improve the emission estimates but require reliable emission patterns as prior information. To serve this urgent need, we developed a high-resolution (0.25 0.25) methane emission inventory for China's coal mining using a recent publicly
