The Coal Mining Heritage of Lafayette
The Coal Mining Heritage of Lafayette From the late I 880s until the I 930s, Lafayette was a major coal town. Read the history of the coal mining era, examine the location of coal mines within the Lafayette area, and enjoy historic photos of the Waneka Lake Power Plant and the Simpson Mine with the attached Coal Mines of the Lafaveti’e Area brochure. This brochure was created by the Lafayette Historic Preservation board, and it highlights the fascinating Coal Mining Heritage of Lafayette. oft/ic — • Coal Mines Lafayette Area page 1 • Coal Mines of the Lafayette Area - page 2 • Coal Mines f the Lfa)’ette Area — map ____________________________ Historic Preservation Board, City of Lafayette, Colorado The social legacy. The social legacy of mining is equally important to contemporary Lafayette The mines required far more labor than was available locally and quickly attracted experienced miners and laborers from Europe and other parts of the U.S. The result was a community comprised of many ethnic groups, including Welsh, English. Scottish, Irish, central European, Hispanic, Italian, and Swedish workers and their families. Local farmers and ranchers also shared in the coal boom and worked as miners in the winter when coal production was high and agricultural work slow. A sense of this ethnic diversity can be gained by walking through the Lafayette cemetery at Baseline and 111th Street. The variety of family names gives a sense of the many nationalities that have contributed to Lafayette’s history. Although the mining life was hard, families were fun-loving and many social activities centered around schools and churches. -

Characteristics of Early Cretaceous Wildfires in Peat-Forming Environment, NE China Shuai Wang, Long-Yi Shao*, Zhi-Ming Yan, Ming-Jian Shi and Yun-He Zhang
Wang et al. Journal of Palaeogeography (2019) 8:17 https://doi.org/10.1186/s42501-019-0035-5 Journal of Palaeogeography ORIGINAL ARTICLE Open Access Characteristics of Early Cretaceous wildfires in peat-forming environment, NE China Shuai Wang, Long-Yi Shao*, Zhi-Ming Yan, Ming-Jian Shi and Yun-He Zhang Abstract Inertinite maceral compositions in coals from the Early Cretaceous Erlian, Hailar, and Sanjiang Basins in NE China are analyzed in order to reveal palaeowildfire events and palaeoclimate variations. Although huminite is the dominant maceral group in the studied basins, the inertinite group, as a byproduct of palaeowildfires, makes up a considerable proportion. Occurrence of inertinite macerals indicates that wildfires were widespread and frequent, and supports the opinion that the Early Cretaceous was a “high-fire” interval. Inertinite contents vary from 0.2% to 85.0%, mostly within the range of 10%–45%, and a model-based calculation suggests that the atmospheric oxygen levels during the Aptian and Albian (Early Cretaceous) were around 24.7% and 25.3% respectively. Frequent fire activity during Early Cretaceous has been previously related to higher atmospheric oxygen concentrations. The inertinite reflectance, ranging from 0.58%Ro to 2.00%Ro, indicates that the palaeowildfire in the Early Cretaceous was dominated by ground fires, partially reaching-surface fires. These results further support that the Cretaceous earliest angiosperms from NE China were growing in elevated O2 conditions compared to the present day.

The minimum oxygen content As a byproduct of peatland evolution under the common that can support combustion in nature is 15% (Belcher influence of geological conditions including palaeoclimate, and McElwain 2008). -
Proposal for Development of Dry Coking/Coal
Development of Coking/Coal Gasification Concept to Use Indiana Coal for the Production of Metallurgical Coke, Liquid Transportation Fuels, Fertilizer, and Bulk Electric Power Phase II Final Report September 30, 2007 Submitted by Robert Kramer, Ph.D. Director, Energy Efficiency and Reliability Center Purdue University Calumet Table of Contents Page Executive Summary ………………………………………………..…………… 3 List of Figures …………………………………………………………………… 5 List of Tables ……………………………………………………………………. 6 Introduction ……………………………………………………………………… 7 Process Description ……………………………………………………………. 11 Importance to Indiana Coal Use ……………………………………………… 36 Relevance to Previous Studies ………………………………………………. 40 Policy, Scientific and Technical Barriers …………………………………….. 49 Conclusion ………………………………………………………………………. 50 Appendix ………………………………………………………………………… 52 2 Executive Summary Coke is a solid carbon fuel and carbon source produced from coal that is used to melt and reduce iron ore. Although coke is an absolutely essential part of iron making and foundry processes, currently there is a shortfall of 5.5 million tons of coke per year in the United States. The shortfall has resulted in increased imports and drastic increases in coke prices and market volatility. For example, coke delivered FOB to a Chinese port in January 2004 was priced at $60/ton, but rose to $420/ton in March 2004 and in September 2004 was $220/ton. This makes clear the likelihood that prices will remain high. This effort that is the subject of this report has considered the suitability of and potential processes for using Indiana coal for the production of coke in a mine mouth or local coking/gasification-liquefaction process. Such processes involve multiple value streams that reduce technical and economic risk. Initial results indicate that it is possible to use blended coal with up to 40% Indiana coal in a non recovery coke oven to produce pyrolysis gas that can be selectively extracted and used for various purposes including the production of electricity and liquid transportation fuels and possibly fertilizer and hydrogen. -

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.
