Analysis Of Coal In Different Mines Of Korba District Pdf Download [BEST]

Sub-areas of Korba Coalfield are: Korba, Surakachhar, Rajgamar, Manikpur, Dhelwadih, Kushumunda and Gevra. The major working coalmines are: Surakachhar, Banki, Balgi, Rajgamar, Pavan, Manikpur, Dhewadih, Singhali, Bagdeva, Kusumunda, Laxman, Gevra and Dipka.[5]

The main sources of pollution in the Korba area are coal-based power plants, smelter and open cast mines at Gevra, Dipka and Kusmunda. Large scale transportation of coal raises a pollution problem. Amongst steps taken or underway to check pollution in the area are: widening and repairs of roads in Gevra, Dipka and Kusmunda mines and procurement of Continuous Ambient Air Monitoring Stations at Gevra and Dipka mines.[11]

There are several coal-based thermal power stations in the area consuming coal from Korba Coalfield. Korba Super Thermal Power Plant of NTPC has installed capacity of 2,600 MW. It gets coal from Gevra and Kusmunda mines.[20]Chhattisgarh State Power Generation Company Limited has three power stations in the area: Korba East Thermal Power Station has installed capacity of 440 MW, Dr. Shyama Prasad Mukherjee Thermal Power Station (Korba East) 500 MW, and Hasdeo Thermal Power Station (Korba West) 840 MW.[21] The captive power plant of Balco (BCPP) has an installed capacity of 270 MW.[22] It is coming up with a 1,200 MW power expansion project.[23]

A geochemical study of the trace metals and lead isotopic ratios of soil and sediments in Korba, Chhattisgarh, India is presented here for the first time. Korba, the nation's 'power hub' is also the fifth among its eighty-eight most critically polluted industrial hotspots. A very high mean concentration (in mg kg-1) of V (308), Cr (567), Mn (3442), Co (92), Cu (218), Zn (426), Pb (311), Th (123) and U (32) characterized the sediments of the studied area with mean Igeo values of the trace metals ranging from -2.29 to 3.27. In the two-ratio scatter Pb isotope plot of the different environmental matrices, except for human blood, coal, soil, sediments, non-washed leaves, flyash and diesel overlapped linearly in the mixing line between diesel as the highest anthropogenic end member and a core sediment fraction representing its geogenic counterpart. The mean 207Pb/206Pb Pb ratio decreased in the order of diesel (0.9012) > flyash (0.8757) > coal (0.8498) soils and sediments (0.8374) > lowest core sediment fraction (0.8017). Principal Component Analysis (PCA) of the trace metal data extracted V, Cr, Cu, Zn, Pb, U and Th in the first component PC1. The northeastern part of the study area revealed major hotspots of V, Cu, Co, Zn and Pb near the flyash dykes of the power stations. Human blood used as a biomarker for Pb pollution in this study had a mean blood lead level of 28 g/dl with a distinctive high 207Pb/206Pb ratio of 0.8828.

The power hub of Chhattisgarh, Korba district, is situated two hundred km from the state capital Raipur. It has seen rapid industrial growth in the past 15-20 years due to coal mining. Currently, there are seven coal mines, 12 thermal power plants and other industries operating within 25 kilometres of the district.

The Dipka Mines, owned by South Eastern Coalfields Limited (SECL), is the thirdlargest coal mine in the country. It spreads over 1,999 hectares of land across 10 villages, namely Dipka, Chainpur, Beltikri, Jhingatpur, Jhabar, Sirki, Renki, Suvabhondi, Ratiza and Malgaon, in Korba district. According to a 2019 company report, the project has affected at least 1,690 families. Those displaced continue to demand rehabilitation, fair compensation and employment opportunities.Land acquisition for the project was completed in phases between 1986 and 2004. Since then, SECL has applied multiple times to expand the mining area and its capacity. However, reportedly, only some of the affected families have been resettled and compensated for the land they gave up. The village residents have time and again voiced their concerns about the polluting and destructive impact of the mining activities on the land and water sources. Amongst other issues, they claim that mining is turning the land uncultivable. However, in Korba district, Dipka is only one of the many mines responsible for polluting the environment. In March 2016, the villagers affected by the Dipka Mines came together with the projectaffected people from Gevra and Kusmunda mining projects to protest against the management of SECL. They raised their concerns with the support of local political outfits and activists. In a meeting, they decided against giving up their lands for the mine expansion and planned to submit their concerns to the district collector, reported a newspaper. In January 2017, the affected villagers launched fresh protests to stop blastingrelated work in different areas of the mining site. In June, the protesters appealed to the administration to shut down the mine if it was unable to meet the demands for rehabilitation, compensation and employment. In the same year, SELC submitted a proposal to expand the capacity of the mines from 31 MTPA (million tonnes per annum) to 35 MTPA to meet national demands. In February 2018, the Ministry of Environment, Forests and Climate Change granted the environmental clearance to the project. However, an environmental activist, Laxmi Chouhan, challenged the decision in the National Green Tribunal (NGT) for being illegal, improper and irregular". In September 2019, Dipka Mine was flooded after the Lilagar river changed course. The mine was temporarily submerged, which triggered questions over the condition of the mines as a potential hazard zone. According to a 2019 news report, the environmental concerns of the project are glaring. It restated that the coal dust is worsening the air quality in the area and severely polluting the river water. The activists have also underlined the impact of ongoing mining activities on the regions topography. In March 2019, the NGT directed the Central Pollution Control Board to act upon the problem of pollution resulting from poor transportation for mining activities. In June, the Chhattisgarh high court dismissed a petition filed against the SELC by the Chhattisgarh Environment Conservation Board. In January 2020, the affected people submitted a letter to the environment ministry to highlight the socioenvironmental degradation caused by mining and requested the ministry to not grant an extension to the mine. Despite this, the ministry approved an extension of 30 years in March while failing to account for many of the concerns raised. Later that year, in one of the villages, the protesters took out a rally to the office of the SELCs general manager to protest against the pollution. They also pointed towards the poor condition of the roads. The police and administration had to intervene after some protesters locked the general manager in his office. On August 7, 2020, during the NGT hearing, the appellant argued against the expansion of the mine and demanded withdrawal of the environmental clearance to the project. In May 2021, a newspaper reported that the expansion work for the mine was still ongoing. Meanwhile, the villagers could not register their opposition due to restrictions imposed by the COVID19 pandemic lockdown. Currently, SECL has applied to further increase the capacity of the mines to 40 MTPA. 006ab0faaa
