For these reasons, coal beds of the Douglas group have not been extensively mined by strip mining method Drift and Slope Mining In localities where the coal available at the surface has been exhausted by stripping or is of poor quality, drift or slope mining is generally employedKGS--Coal Resources of the Douglas Group--Introduction,A report on post-Cherokee coal deposits of Kansas, by R E Whitla (1940), contains some descriptions of mines and mining in coal beds of the Douglas group A chapter on coal by J M Jewett (Jewett and Schoewe, 1942) is included in Kansas Mineral Resources for Wartime Industries geographical maps of coal mines - abwasseranlageneu,KGS--Coal Resources of the Douglas Group--Geography Geography Recent Trends Mining Methods Douglas Group Map of eastern Kansas showing outcrop area of Douglas rocks Coal, Kentucky Geological Survey, University of Kentucky,Coal petrographers (people who study coal under a microscope) separate macerals into three groups, each of which includes several maceral types The groups are inertinite, liptinite, and vitrinite These groups were defined according to their grayness in reflected light under a microscope Liptinites are dark gray, vitrinites are medium to light gray, and inertinites are white and can be very brightCoal, Kentucky Geological Survey, University of Kentucky,Surface Mining Surface-mining methods include area, contour, mountaintop removal, and auger Area mines are surface mines that remove shallow coal over a broad area of fairly flat landEffects of Coal Mining on the Water Resources of the ,Effects of Coal Mining on the Water Resources of the Tradewater River Basin, Kentucky By HAYES F GRUBB and PAUL D RYDER GEOLOGICAL SURVEY WATER-SUPPLY PAPER 1940Coal, Kentucky Geological Survey, University of Kentucky,Ultimate analysis provides a convenient method for reporting the major organic elemental composition of coal For this analysis, a coal sample is combusted in an ultimate analyzer, which measures the weight percent of carbon, hydrogen, nitrogen, sulfur, and ash from a coal sampleCoal mining | GeoKansas,Underground mining was dominant there for several decades, and the Weir-Pittsburg coal bed became the most extensively mined coal bed in Kansas history Big Brutus museum Strip mining became the preferred method in southeastern Kansas in the 1930s, although underground mining continued there until 1960 and in Osage County until 1964What are the main methods of mining? | American ,In-situ mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth enough money to justify extracting itCoal Mining and Processing - The National Academies Press,Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal
