Abundant pore space in coal is not only the place for accumulation of coalbed methane (CBM), but also tunnel gas migration. In this study, five sets samples before and after second coalification were selected from eastern margin Ordos Basin to simulate supercritical CO 2 (Sc-CO ) extraction equipment. The evolutions structure porosity tested by mercury intrusion porosimetry nuclear magnetic res...

Work is focused to the study of unburned carbon in ash from coal (and wastes) combustion in 8 combustion tests at 3 fluidised-bed power station, at co-combustion of coal and wastes (also at fluidized bed) and at bench-scale unit simulating coal combustion in small domestic furnaces. The attention is paid to unburned carbon contents in bottom ashes and fly ashes at these 8 combustion tests and t...

Coal is a porous medium with complex pore structures. The characteristics of the pore structure play an important role in various aspects of coal use, including extraction of methane from coal seams, CO2 sequestration in coal, and water purification by activated carbon. To describe comprehensively the pore structure of coal, we apply transmission electron microscopy (TEM) and synchrotron small-...

Demand for a cleaner source of energy is increasing in India. In the search alternate sources, coal bed methane gas receives considerable attention its potential as good source. During coalification process, captured seams and later released during mining operations. Coal separation crucial both economic benefit emission reduction. The production from an efficient way to reduce greenhouse emiss...

The accident in the Rasa mines of 28 February 1940 was the greatest tragedy in the history of mining in Istria; an explosion, most likely fuellled by methane and coal dust, claimed 185 lives and injured over a hundred people. Documentation made available by the courtesy of Zdravko Hrastnik, a collector from Labin, and the archieves of the Vicenza town hospital shed some light on this tragedy an...

Preface On its way to its current form this report has received significant input from a considerable number of experts. In particular, a panel of experts in Brussels discussed a draft version of the report on March 29, 2000 (see Annex 5 for a list of names), and made a number of specific and more general comments and suggestions. The authors would like to thank these people for their valuable ...
