  • Update on Lignite Firing
    Update on lignite firing Qian Zhu CCC/201 ISBN 978-92-9029-521-1 June 2012 copyright © IEA Clean Coal Centre Abstract Low rank coals have gained increasing importance in recent years and the long-term future of coal -derived energy supplies will have to include the greater use of low rank coal. However, the relatively low economic value due to the high moisture content and low calorific value, and other undesirable properties of lignite coals limited their use mainly to power generation at, or, close to, the mining site. Another important issue regarding the use of lignite is its environmental impact. A range of advanced combustion technologies has been developed to improve the efficiency of lignite-fired power generation. With modern technologies it is now possible to produce electricity economically from lignite while addressing environmental concerns. This report reviews the advanced technologies used in modern lignite-fired power plants with a focus on pulverised lignite combustion technologies. CFBC combustion processes are also reviewed in brief and they are compared with pulverised lignite combustion technologies.

  • Seasonal Assessment of Groundwater Contamination in Coal Mining Areas of Balochistan
    sustainability Article Seasonal Assessment of Groundwater Contamination in Coal Mining Areas of Balochistan Ayesha Ayub and Sheikh Saeed Ahmad * Department of Environmental Sciences, Fatima Jinnah Women University, The Mall, Rawalpindi 46000, Pakistan; [email protected] * Correspondence: [email protected]; Tel.: +923215167726 Received: 11 July 2020; Accepted: 18 August 2020; Published: 25 August 2020 Abstract: Balochistan is a semi-arid region. The assessment of water quality is very important, as the majority of people depend on groundwater for drinking purposes. The present study involves the quality assessment and mapping of drinking water in the five selected major coal mining sites in the four districts of Balochistan. A total of 50 samples were collected from these five coal mining sites in two seasons: i.e., summer and winter. A physicochemical analysis was carried out for groundwater - - 2+ samples: i.e., pH, electrical conductivity (EC), total dissolved solid (TDS), CO3, HCO3 , Cl , Ca , Mg2+, Na+,K+, Cd, Cr, Co, Cu, Fe, Pb, Mn, Hg, Ni, and Zn. Thematic maps were used to depict the spatial distribution of significant variables and were compared with WHO standards (2011) during both seasons. The majority of parameters crossed the safe permissible limit of WHO standards. The water quality index (WQI) was calculated for the whole monitoring data obtained from both seasons from the perspective of drinking water in each of the selected sites. Moreover, a principle component analysis (PCA) and correlation matrix was carried out for the data analysis in order to identify the source of pollution and correlation among the variables. The results suggested that the overall quality of water from the selected coal mining sites deteriorated due to the overexploitation of coal mines and mining activity.

  • Chapter 1. Overview: Coal Ash Beneficial Use and Mine Land Reclamation
    CHAPTER 1. OVERVIEW: COAL ASH BENEFICIAL USE AND MINE LAND RECLAMATION Alfred D. Dalberto, Barry E. Scheetz, Roger J. Hornberger, Timothy C. Kania, Michael J. Menghini, Scott E. Walters 1.1 INTRODUCTION—PENNSYLVANIA’S ABANDONED MINE LAND PROBLEM Since commercial coal mining began in Pennsylvania prior to 1800 (Dodge & Edwards, 2003), the Commonwealth’s miners have extracted approximately 16.3 billion tons of coal from the Anthracite and Bituminous Coal Fields combined (PA DEP, 2002). The efforts of Pennsylvania’s miners helped fuel the nation’s industrial revolution and fed families for generations. However, the other legacy of the state’s rich mining heritage is an unparalleled abandoned mine land (AML) problem. Prior to the enactment of the federal Surface Mining Control and Reclamation Act (SMCRA) in August 1977, laws and regulations governing surface mining and the surface effects of underground mining, were largely ineffective in achieving reclamation of mined lands. SCMRA, which applies to all surface mining conducted after August 1977, requires complete reclamation of surface mine-affected lands and requires the posting of financial assurances, usually in the form of bonds, to ensure reclamation. While present-day mine sites are occasionally abandoned, the Pennsylvania Department of Environmental Protection (DEP) has well-established programs in place to reclaim those sites. However, much of the vast AML problem from the pre-1977 mining remains. There are more than 5000 abandoned, unreclaimed mine problem areas encompassing more than 189,000 acres in Pennsylvania, according to the DEP Bureau of Abandoned Mine Reclamation (BAMR). BAMR’s inventory of abandoned mine sites also identifies over 820 abandoned coal refuse piles.

  • Maceral Types and Quality of Coal in the Tuli Coalfield: a Case
    applied sciences Article Maceral Types and Quality of Coal in the Tuli Coalfield: A Case Study of Coal in the Madzaringwe Formation in the Vele Colliery, Limpopo Province, South Africa Elelwani Denge * and Christopher Baiyegunhi Department of Geology and Mining, University of Limpopo, Private Bag X1106, Sovenga 0727, South Africa; [email protected] * Correspondence: [email protected] Featured Application: Authors are encouraged to provide a concise description of the specific application or a potential application of the work. This section is not mandatory. Abstract: The Madzaringwe Formation in the Vele colliery is one of the coal-bearing Late Palaeozoic units of the Karoo Supergroup, consisting of shale with thin coal seams and sandstones. Maceral group analysis was conducted on seven representative coal samples collected from three existing boreholes—OV125149, OV125156, and OV125160—in the Vele colliery to determine the coal rank and other intrinsic characteristics of the coal. The petrographic characterization revealed that vitrinite is the dominant maceral group in the coals, representing up to 81–92 vol.% (mmf) of the total sample. Collotellinite is the dominant vitrinite maceral, with a total count varying between 52.4 vol.% (mmf) and 74.9 vol.% (mmf), followed by corpogelinite, collodetrinite, tellinite, and pseudovitrinite with a Citation: Denge, E.; Baiyegunhi, C. count ranging between 0.8 and 19.4 vol.% (mmf), 1.5 and 17.5 vol.% (mmf), 0.8 and 6.5 vol.% (mmf) Maceral Types and Quality of Coal in the Tuli Coalfield: A Case Study of and 0.3 and 5.9 vol.% (mmf), respectively. The dominance of collotellinite gives a clear indication Coal in the Madzaringwe Formation that the coals are derived from the parenchymatous and woody tissues of roots, stems, and leaves.
