“…Previously several studies on the coals from five coal basins in terms of their palynological (Akhtar and Kosanke 2000), petrological, geological, sedimentological (Hossain et al 2014Bostick et al 1991;Islam et al 1992;Bakr et al 1996;Islam 1998;Imam et al 2002;Farhaduzzaman et al 2012;Farhaduzzaman et al 2013a, b;Islam and Hayashi 2008;Uddin et al 2016), radiological, thermal and geochemical properties (Habib et al 2019a;Islam et al 2011;Haider et al 2011;Podder et al 2004) applying HPGe gamma spectrometry, EDXRF, PIXE, LIBS, and INAA techniques and CCRs characteristics and its potential uses (Howladar and Islam 2016) have been carried out. Besides, several studies on Barapukuria soils suggested that it was intensively contaminated with trace elements released from the coal matrix owing to the coal mining activities (Hossain et al 2015Zakir et al 2013Zakir et al , 2017Zakir and Arafat 2020;Bhuiyan et al 2010b, b;Halim et al 2015, Halim et al 2013) employing EDXRF and AAS techniques for environmental studies.…”

“…Considering the negative impacts on human health and on the environment caused by NORMs from CTP, it is important to study the radiological risks of NORMs in coals, CCRs, and soils. The average values of radiological risk indices in CCRs from BTPP was 447 AE 95 Bqkg À1 for radium equivalent activity (Ra eq ), 1.2 AE 0.3 for external hazard index (H ex ), 201.1 AE 42.2 nGy h À1 for absorbed gamma dose (D), 0.25 AE 0.05 mSv year À1 for annual effective dose (E) and 8.6 Â 10 À4 AE 1.8 Â 10 À4 S v À1 for excess lifetime cancer risk (ELCR), most of which are higher than the permissible limits (Habib et al 2019a). However, in soil samples around the BTPP, the average Ra eq (in BqÁkg À1 ), D (in nGy h À1 ), H ex , E (in mSvÁyear À1 ) and ELCR are 250 AE 22, 114 AE 9, 0.67 AE 0.06, 0.20 AE 0.02, and Fig.…”

To represent a comprehensive scenario regarding the coal mining and coal-fired power plant activities in a developing country (Bangladesh) and to understand the total environmental impacts, potential coal resources of Bangladesh, environmental geochemistry and dispersion of pollutants, eco-toxicological impacts, human health risks as well as socioeconomic impacts are evaluated in this chapter. Potential coal reserves along with the future plants are estimated. Technogenic sources of environmental pollutants including environmentally toxic heavy metals, health hazardous radionuclides, persistent organic pollutants, suspended particulate maters, etc. are assessed. In doing so, scarce associated data from coal mine (Barapukuria, Bangladesh) and Barapukuria coal-fired power plant (BTPP) of Bangladesh have been reconciled by using and arguing the previous works around the globe. Immense and proper literature reviews as well as the existing data on Barapukuria coal mine and BTPP are tabulated to compare and understand the condition along with the potential prevention and remediation approaches.

“…Zhou et al [8] studied the environmental geochemical characteristics of trace elements and natural radioactive elements around coal gangue piles, and found that Cu, Ni, and Pb were enriched in soybeans in the study area, and natural radioactive elements would increase the health risks of respiratory system. Habib et al [9] aiming to coal and coal-fired residues in coal-fired power plants carried out radioactivity assessment, and found that the radioactivity of coal-fired residues is highly polluted, which may pose a radiation threat to the local environment. Habib et al [10] evaluated the distribution of natural radionuclides and their potential radioactive risks in the surrounding soil of coal-fired power plants.…”

The accumulation/improper treatment of coal gangue will not only lead to waste of land, but also cause environmental pollution. Especially the impact of radioactive elements on the surrounding ecological environment is widely concerned by many scholars. In this study, the concentration of radioactive elements (uranium (U) and thorium (Th)) of small-scale coal gangue mining site and surrounding soil in the northern region of Xieqiao coal mine were tested, the material composition of coal gangue was analyzed via XRF and XRD, the modes of occurrence of U and Th elements were investigated, and their potential ecological risks and ecological effectiveness were evaluated. The results show that the clay minerals with high content in coal gangue are the key minerals for the adsorption of uranium and thorium in coal gangue. The specific activity of two radioactive elements (U and Th) in soil is much lower than that of coal gangue. With the increase of the distance from the soil collection point to the gangue piles and the depth of the soil profile, the specific activities of the two radioactive elements decrease gradually. On the basis of the concentration curve, the range of the radioactive contamination halo of gangue piles is limited (≤30 m), speculating qualitatively that the gangue dump has no significant influence on the radioactivity of the surrounding water. The modes of occurrence of U and Th in coal gangue and soil are altered. According to the index of geo-accumulation, Th is easier to accumulate in soil environment, but Th and U pollution in soil is not obvious. In contrast to U element, the active state of Th element in soil is generally affected by exogenous (coal gangue) export, which may have a potential environmental effects. This study provides a research idea for the investigation of radioactive element pollution to the surrounding soil in small-scale coal gangue plies.

“…Thus, it is easy to cause the spontaneous combustion of coal. For example, in June 2012, a serious fire occurred in the Shendong Bulianta Coal Mine due to the spontaneous combustion of coal seams in goaf areas, and such major disasters have also occurred in the goaf area of the 1101 fully mechanized mining face of the Barapukuria Coal Mine in Bangladesh. , …”

Study on the Oxidation Kinetics and Microreactivity of Water-Immersed Coal

Both the macroscopic reaction and microscopic characterization of water-immersed coal have been studied. The methods of thermogravimetric analysis via Fourier transform infrared spectroscopy (TG-FTIR) and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) are used. The apparent activation energy of water-immersed coal was significantly lower than that of raw coal. For the same coal sample, the production of CO in water-immersed coal is significantly higher than that in raw coal. The analysis shows that after water immersion, the content of hydroxyl and aromatic hydrocarbons in the coal increases significantly and the temperature at which fat-based and oxygen-containing functional groups participate in the reaction decreases. This indicates that the functional groups are unstable after water immersion and react violently. When the immersion time is 60 days, the activation energy is the lowest, the production of CO reaches its maximum, and the variation of each functional group is most obvious.
