15 Μαΐ 2016 · Measurements to determine coal quality as fuel include proximate analysis, ultimate analysis and calorific value. The latter is an attribute taking non-negative real values, so a simple transformation is sufficient for its spatial modeling applying geostatistics.
15 Μαΐ 2016 · Mapping of coal quality using stochastic simulation and isometric logratio transformation with an application to a Texas lignite. International Journal of Coal Geology, 152, 80–93. View Abstract
3 Ιαν 2022 · Two coals, bituminous (American Baily Pittsburgh No. 6) used in Israeli utilities and lignite (brown coal Hambach) used in German power plants, have been investigated in this study. The results show that the combined TG/DSC method can provide a much better understanding of the chemical reactivity of coals in the combustion process.

1 Ιαν 1995 · The Jackson and Wilcox Groups of eastern Texas (fig. 1) are the major lignite producing intervals in the Gulf Region. Within these groups, the major lignite-producing formations are the Paleocene-Eocene Calvert Bluff Formation (Wilcox) and the Eocene Manning Formation (Jackson).
1 Μαΐ 2016 · Drill hole datasets ranging from widespread exploration drilling to detailed development drilling from a lignite deposit in Texas were used to illustrate the modeling.
Near-surface lignite occurs in two elongate bands stretching from the Rio Grande (Webb and Starr Counties) to the Red River (Bowie County) and Angelina River (Angelina County). Deep-basin lignite occurs coastward and downdip from the near-surface occurrences.
