Coal mining is the prime reason behind climate change and has a great impact on global warming as coal produces 39℅ global CO2 emissions. At the same time, coal production is the chief factor of 40% of the world’s electricity including economic development. The purpose of the present study is to the worldwide, national & endemic impact of coal mining on ambient air in respect of global warming. A number of peer-reviewed, research articles, reviews, and reports were collected from 1970 to 2022 employing a keyword-based search. The articles compiled were analyzed globally & indigenously and assorted according to the selected browsers addressed & the methodological approach adopted. Coal mining activities emit toxic gases into the atmosphere and hence decline the ambient air quality. The crucial Greenhouse gases contribute to the overall warming of the earth. Coal continues to be the distinctive and long-term resource of the world energy supply hence its mining-related pollution mitigation and the reclaiming of the environment are necessary. In present circumstances, it is obligatory to implement Clean Coal Technologies i.e. sustainability in energy production & its utility. Abandoned mine wasteland restored and converted into vegetative land may also solve numerous major issues like lessening GHGs, GW, and prevention of degraded wasteland.

Phytoremediation is using live plants to remove toxins and contaminants from land, water, or the air. Hydrocarbons, radionucleotides, fertilizers, explosives, heavy metals, and other contaminants are all efficiently removed from wastewater by this approach. Aquatic plants can be classified as free-floating, emergent, or submerged. Studies have been done on the capacity of Pontederia crassipes Mart. to extract pollutants like dissolved solids, and heavy metals from wastewater. The pollution of chromium in Indian chromite mining sites has also been addressed it and following phytoremediation, the biomass may be utilized to produce vermicompost, biogas, and bioethanol. Surface mining is producing changes in land use, land cover, and climate in the RCF area of West Bengal, India. By using aquatic plants to phytoremediate pit lakes (PLs), fresh water can be produced and chances for sustainable livelihoods can be created. The population in former mining regions has grown significantly, leading to the relinquishment of agriculture and the development of illegal mining and coal theft. This study aims to examine the literature on aquatic plant phytoremediation of water, emphasizing the necessity of phytoremediation of PL water in RCF and the potential applications of Pontederia crassipes Mart. biomass for the generation of biogas, bioethanol, and vermicompost.

“…Eastern Coalfield is a store-house for good-quality coal, catering to both the steel sector and thermal power plants. The geological aspects of this geographical location have been extensively studied, along with the mineralogical distribution (Chatterjee and Pal 2010;Das and Chakrapani 2011;Saha et al 2022). A preliminary analysis of coal samples from Eastern coalfield gave promising results with respect to REE concentrations (unpublished results).…”

The extraction of valuables from waste has gained momentum. Thermal influence alters both the organic and inorganic components of coal. Insufficient knowledge on the association of rare earth elements (REEs) with the parent matrix of thermally altered high-ash coals (63% ash) limits the potential for such coals being utilized for isolation of valuables. In this study, we analyzed the distribution and occurrence modes of REEs within a magmatically altered high-ash coal via nine-step sequential extraction, combining Tessier and BCR methods. The total concentration of REEs in the coal sample, on whole coal basis, was found to be 820 ppm, which is significantly higher than the world average. Major mineral oxides were deduced to be those of Si, Fe, Al, Ca, Mg, and Ti. Sequential extraction confirmed that about 66% of HREE and 25% of LREE were included in the residual fraction. LREEs were concluded to be primarily in ionic form, whereas HREEs were speculated to be associated with the TiO2 phase. XRD analyses showed that thermal alteration affected the dolomite phase specifically, which selectively got removed where carbonate-bound elements were assessed. Petrographic analysis supported the magmatic influence and demonstrated the presence of mosaic structures and pores containing unfused vitrinite, with a reflectance value of 3.6. To summarize, the present study pertaining to delineation of association of valuables in high-ash heat-altered coals from an Eastern coalfield in India can potentially open up new avenues for utilizing such coals, which are otherwise considered waste.
