Geochemical, Mineralogical, And Structural Characteristics Of Coal From The Gare Pelma Coalfield, Chhattisgarh, India

Abstract

A variety of analytical methods are used in coal testing to assess the characteristics and makeup of coal. These tests are crucial for figuring out the quality, energy potential, and appropriateness of coal for different uses. In this study study we take four different grade of subbituminous coal samples are collected from Gare Pelma 4/2&3 Mines and we studied. It’s moisture content, ash percentage, volatile matter content. We took four different grade samples of grade-17, grade-14, grade-12, grade-11, out of these four samples, sample number 04 has highest carbon percentage with highest Gross Calorific Value (GCV) -4070 Kcal/Kg, moisture% 5.00, ash% 37.86, volatile matter% 25.84 so this coal is considered as the best coal for power generation. The elemental composition also known as Ultimate analysis by SEM/EDAX and chemical structure of coal by XRD. Analytical techniques such as gross calorific value(GCV), proximate analysis (which measures moisture, volatile matter, ash, and fixed carbon) and ultimate analysis (which determines elemental composition like C, H, O, N, and S) help classify coal types and assess their energy potential and environmental impact. X-ray diffraction (XRD) is used to study the crystalline and amorphous phases in coal, particularly to identify mineral content and the degree of structural ordering in carbon-rich components. This study helps in optimizing the combustion efficiency, reduce emission and also ensure cost effective energy production. When we use this type of grading coal for the power generation, then we get less pollution and good environmental performance. The economic significance of coal, the challenges of switching to alternative energy sources, and the potential future of coal mining in the context of international efforts to combat climate change are also covered.
