The occurrence of coal is related directly to the climate of a given geological age which, in turn, is determined by the extent of the seas, regional geography, the configuration of the land masses and therefore, by the ongoing process of continental drift. Of major importance also is the ...
prolonged submergence of large areas and regions. The emergence of land vegetation in the Lower Paleozoic and the evolution of the vegetation in subsequent earth history were of great importance for coal formation. Humic coals are found in sedimentary beds beginning with the Silurian, and industrially...
India has a vast energy infras- tructure of coal, starting from coal mining to extraction to coal transport and on to coal utilization in power plants. The JCST special issue on Indian coal will be of great importance as a compilation of some of the important R&D aspects of Indian coals ...

Finally, the advantages and disadvantages of different preparation methods are identified. To make the industrial applications of coal-based anode materials for sodium-ion batteries more viable, the importance of the de-ashing process is introduced....
Dust formation of the materials is a problem of great practical importance for the mining industry. Indeed, the powders of coal particles formed during crushing may cause not only explosions in mines but they also contaminate the environment around the roads of the coal transportation. In this ...
In correlation and regression analysis, the moisture content shows a reverse correlation with GCV (Regression value of R2=0.68). This study helps researchers to comprehend the importance of Colombian coals and presents various techniques for characterisation of coals.Segun A. Akinyemi...
