Development of a petrographic classification of fly-ash components from coal combustion and co-combustion. (An ICCP Classification System, Fly-Ash Working Group – Commission III.)

International Journal of Coal Geology > 2017 > 183 > C > 188-203

A new system for the microscopic classification of fly-ash components has been developed by the Fly-Ash Working Group, Commission III of the ICCP and is presented herein. The studied fly-ashes were obtained from the combustion of single coals of varied rank, coal blends, and coals blended with other fuels (biomass, petroleum coke), in different operating conditions and by means of different technologies...

Identification of alginite and bituminite in rocks other than coal. 2006, 2009, and 2011 round robin exercises of the ICCP Identification of Dispersed Organic Matter Working Group

J. Kus, C.V. Araujo, A.G. Borrego, D. Flores, more

International Journal of Coal Geology > 2017 > 178 > C > 26-38

The paper presents results of round robin exercises on photomicrograph-based identification of dispersed organic matter in source rocks that represent a range of marine and lacustrine deposits from worldwide localities and cover a range of thermal maturities. The round robin exercises were conducted by the Identification of Dispersed Organic Matter Working Group (IDOM WG) of the International Committee...

Distribution of phenols related to self-heating and water washing on coal-waste dumps and in coaly material from the Bierawka river (Poland)

Á. Nádudvari, M. J. Fabiańska, M. Misz-Kennan

Mineralogia > 2015 > Vol. 46, iss. 1/2 > 29--40

Several types of coal waste (freshly-dumped waste, self-heated waste and waste eroded by rain water), river sediments and river water were sampled. The aim was to identify the types of phenols present on the dumps together with their relative abundances. Gas chromatography-mass spectrometry (GC-MS) analyses of a large number of samples (234) statistically underpin the phenol distributions in the sample...

Classification of liptinite – ICCP System 1994

W. Pickel, J. Kus, D. Flores, S. Kalaitzidis, more

International Journal of Coal Geology > 2017 > 169 > C > 40-61

The liptinite maceral group has been revised by ICCP in accordance with the ICCP System 1994. After the revision of the classifications of vitrinite (ICCP, 1998), inertinite, (ICCP, 2001) and huminite (Sykorova et al., 2005) this liptinite classification completes the revised ICCP maceral group classifications. These classifications are collectively referred to as the “ICCP System 1994”. In contrast...

Application of reflectance parameters in the estimation of the structural order of coals and carbonaceous materials. Precision and bias of measurements derived from the ICCP structural working group

S. Pusz, A.G. Borrego, D. Alvarez, I. Camean, more

International Journal of Coal Geology > 2014 > 131 > Complete > 147-161

Optical reflectance of vitrinite is one of the fundamental physical properties that have been used for the study of coal and carbonaceous materials. Organic matter in coals and carbonaceous matter consists mainly of aromatic lamellae, whose dimensions and spatial orientation define its internal structure. Various reflectance parameters describe well the average degree of order of the molecular structure...

S. Cebulak, M. Misz-Kennan, M. Gardocki

Przegląd Górniczy > 2010 > T. 66, nr 1-2 > 96-100

W pracy przeprowadzono porównanie wyników analizy termicznego rozkładu oraz oznaczenia przypadkowej refleksyjności witrynitu i składu maceralnego materii węglowej próbek masy odpadów węglowych ze składowiska kopalni .Rymer.. Badania wykazały znamienne zróżnicowania współzależności termolitycznych i petrograficznych właściwości materii węglowej. Wyniki badań pokazują możliwości dokonywania oceny skutków...

Thermal alterations of organic matter in coal wastes from Upper Silesia, Poland

M. Misz-Kennan

Mineralogia > 2010 > Vol. 41, iss. 3/4 > 105--237

Self-heating and self-combustion are currently taking place in some coal waste dumps in the Upper Silesian Coal Basin, Poland, e.g. the dumps at Rymer Cones, Starzykowiec, and the Marcel Coal Mine, all in the Rybnik area. These dumps are of similar age and self-heating and combustion have been occurring in all three for many years. The tools of organic petrography (maceral composition, rank, etc.),...

Heavy Metals in Mycorrhizal Rhizospheres Contaminated By Zn–Pb Mining and Smelting Around Olkusz in Southern Poland

J. Cabala, P. Krupa, M. Misz-Kennan

Water, Air, & Soil Pollution > 2009 > 199 > 1-4 > 139-149

Soils in areas of mining and smelting of Pb–Zn ores in Southern Poland are strongly enriched in heavy metals (Zn, Pb, Fe, Cd, Tl, As). The highest concentrations of Zn (<55,506 mg kg⁻¹), Pb (<8,262 mg kg⁻¹), Cd (<220 mg kg⁻¹) and Tl (<67 mg kg⁻¹) are linked to the fine fractions of upper soil layers in sites contaminated by past exploitation and processing of ores. The high stress of metals,...
