Exposure of Fluoride in Coal Basin  [PDF]
Khageshwar Singh Patel, Ankit Yadav, Keshaw Prakash Rajhans, Shobhana Ramteke, Reetu Sharma, Irena Wysocka, Irena Jaron
International Journal of Clean Coal and Energy (IJCCE) , 2016, DOI: 10.4236/ijcce.2016.51001
Abstract: Coal is a dirty fuel contaminated with F- and other elements. Several million tons of coal are burnt in Korba basin, central India to generate electricity with pouring fluorine and other elements into the environment. The water is contaminated with F- and other chemicals beyond the permissible limits. The contaminated water is consumed by the human and animals by excreting the balanced toxicants through the stool and urine. Several folds higher concentration of F- in urine (44 mg/L) and stool (266 mg/kg) samples of the cattle are observed. The prevalence of fluorosis diseases in cattle of the Korba basin is reported.

Abstract: A new method of saline soils reclamation using coal powder was proposed and tested in practice in pot experiments on Halaquept soil with alfalfa as a testing plant. The experiment showed the possible applicability of the method in practice.
To the problem of coal mines damping in Ostrava - Karvina basin  [PDF]
Dvo?á?ek Jaroslav
Acta Montanistica Slovaca , 1998,
Abstract: The damping of inefficient mines caused the closure of 4 underground coal mines in the Ostrava-Karviná basin. A time span between the beginning of damping and mining activity finishing can be very short or, on the other hand, relatively long. There are positive and negative consequences in economic and social field in both cases. The contribution analyses the way of damping of these closed underground coal mines on the basis of statistical information.

Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.612124
Abstract: The coal is contaminated with toxic metals at the trace levels. They are released into the environment during mining, handling and burning of coal. The Korba basin has one of the largest coal exploitation areas in the country. In this work, contamination and sources of toxic metals i.e. Hg and Pb in the air, soil and sediment of the Korba basin, India are described. The concentration of Hg and Pb in the ambient air was ranged from 7.4 - 29 and 7.0 - 585 ng/m3 with mean value of 18 ± 4 and 129 ± 104 ng/m3 in the winter season. The mean concentration of Hg in the soil and sediment was 0.22 ± 0.03 and 0.44 ± 0.08 mg/kg, respectively. The higher concentration of Pb in the environmental samples was observed.
Sedimentary conditions for good coal reservoir development in the Carboniferous and Permian, Qinshui Basin
Zhenkui Jin,Chunsheng Wang
Chinese Science Bulletin , 2005, DOI: 10.1007/BF03184078
Abstract: In the Carboniferous and Permian of the Qinshui Basin, coal reservoirs are well developed. But different coal reservoirs are obviously different in distribution, thickness, and reservoir performance etc. This paper studies the factors controlling the development and distribution of good coal reservoirs from the viewpoint of sedimentology and sequence stratigraphy. The study shows that good coal reservoirs are mainly formed in marsh environments on tidal flats and delta plains. The coal reservoirs formed on tidal flats are more continuous laterally than those on delta plains. The fluctuation of sea level shows important control over the vertical and lateral distribution of coal reservoirs. Generally speaking, the coal reservoirs formed in the highstand system tracts are more abundant, thicker and more widespread, and thus the highstand system tracts are more favorable to the formation of good coal reservoirs. The coal reservoirs formed in the transgressive system tracts are lower in abundance, thinner and much less widespread, and thus the transgressive system tracts are not favorable to the formation of good coal reservoirs.
The model of hydrocarbon generation and evolution for coal and macerals in the Tuha Basin
Changyi Zhao,Keming Cheng
Chinese Science Bulletin , 1998, DOI: 10.1007/BF02883382
Abstract: By means of Py-GC,13c NMR and fluorescent analysis, the properties of hydrocarbon generation of rnacerals are determined, and the evolution model of hydrocarbon generation is established for macerals and coal of the Tuha Basin. There are two stages of oil generation for the coal of the Tuha Basin, whoseR° values are 0.40 %–0.80 % and 0.90 %–1.20 % respectively.

Abstract: Recently, commercial coalbed methane production rate has gotten in the Tertiary Powder River basin in USA, which had. lower coal rank and lower gas content, but has higher coal thickness and gas abundance; this made us beginning to considering coalbed methane resource in the lower coal rank basin of eastern Inner Mongolia. Tertiary and Cretaceous coal with a resource of 2 trillion cubic meters was the most important coal accumulated period, which has a thick coal seam, lower coal rank, lower gas content. Through the analysis of Northeast China, we could found that it is important to reinforce study on coalbed methane preservation condition, study on forecasting of high permeable and gas-riched area, secondary biogenesis gas and hydraulic conditions.
Effect of application of coal powder and lime on alfalfa growth on copper polluted acidic soil
Raichev T.,Arsova A.,Popandova S.,J???3zefaciuk G.
International Agrophysics , 2000,
Abstract: The aim of this study was to test the hypothesis that a combined treatment of copper contaminated acid soil with lime and a coal powder decreases copper toxicity due to a synergetic effect of pH increase and association of Cu2+ ions in organo-mineral complexes. A two-year-long pot experiment with alfalfa was carried out on a pseudopodzolic soil contaminated with four Cu levels in the range 0-900 mg kg-1 soil. The amendments applied were lime, coal powder and a precomposted mixture of lime and coal powder. The compost and lime application increased yield and decreased copper content in plants at all levels of copper pollution. Coal powder alone depressed plant growth. The combined application of lime and coal powder maintained soil pH in the optimum range (5.1-5.6) during the whole experiment and had a pronounced effect on yield of the second and next crops, depending on the level of liming.

Michal ?eho?, Petr Vráblík, Jaroslava Vráblíková, Luká? ?i?ka, Eliska Wildova
Journal of Environmental Protection (JEP) , 2017, DOI: 10.4236/jep.2017.813097
Abstract:
Reclamations of dumps in the Most Basin that is located in the North Bohemia consist of restoration of extremely unfavourable properties of rocks that are poured down onto the dump body. These rocks come from the surface layer and the layer where coal bed is present. Sands, clay sands and kaolin (illitic clays) are the main components that occur in the material. Other components are predominantly organic (coal) mass, siderite and pyrite. This report briefly summarizes the history and present of ore, non-metallic and coal mining in the region and addresses in detail the issue of moderating the consequences of mining, which is one of the principal activities of the Research Institute for Brown Coal, j.s.c. in Most. The concept of landscape reclamation in the largest dumps after mining ends, the technical reclamation methodology and the well considered use of fertilizable soil are main results presented in this article.
Coal Waste Powder Amendment and Arbuscular Mycorrhizal Fungi Enhance the Growth of Jabon (Anthocephalus cadamba Miq) Seedling in Ultisol Soil Medium

Jurnal Tanah Tropika , 2013,
Abstract: Coal powder waste application on low nutrient media is expected to be able to increase plant growth and to improve Arbuscular mycorrhizal fungi (AMF) development. The objective of this research was to determine the effect of coal waste powder on the growth of Anthocephallus cadamba Jack and AMF development grown on ultisol soil. Two factors in a completely randomised experimental design was conducted under greenhouse conditions and Duncan Multiple Range Test was used to analyse of the effect the treatment. The first factor was ultisol soil ammended with coal waste powder (control, soil amanded with coal waste 5%, soil amanded with coal waste 10% and soil amanded with coal waste 15%) and the second factor was AMF inoculation (uninoculated control, inoculated with Gigaspora margarita). Plant height, diameter, shoot dry weight, percentage of AMF colonization and nutrient uptake were measured in this experiment. Results of this study showed that coal amendment and AMF when applied separately significantly increased height, diameter, shoot dry weight, root dry weight and nutrient uptake of 12 weeks A. cadamba seedling, but when the coal waste powder and AMF were combined the plant growth parameters were lower than those applied separately but significantly higher than control. The application of coal waste powder or AMF in ultisol soil could increase A. cadamba growth and development.
