Effects of igneous intrusions on coal petrology, .

01.07.2012 · Highlights We compared the influences of igneous intrusions on coal organic composition and pore/fracture. Intrusions result in decrease in vitrinites and increases in inertinites, vacuoles (0.1–10 μm) and microfractures. Contact-metamorphism slightly improves pore development of bituminous coals (< 2.1% VRr). Pores development of altered anthracites (2.1–4.2% VRr) improves with ...

The Coal Bed Methane (CBM), a dreadful mining hazard, became eco-friendly clean gas for the third world country when humanity is facing challenges against pollution and energy crisis. It is observed from the studies that the Korba and Ib valley coals have potential for CBM exploration whereas Umaria coals have negligible potential. Though, the Sohagpur coalfields (east of Umaria coalfield ...

Applied Coal Petrology: The Role of Petrology .

This book is an integrated approach towards the applications of coal (organic) petrology and discusses the role of this science in the field of coal and coal-related topics. Coal petrology needs to be seen as a continuum of organic (macerals) and inorganic (minerals and trace elements) contributions to the total coal structure, with the overprint of coal rank.
