Run-of-mine coal consists of coal, minerals and contami-nants of large particle size. It needs a series of coal prepara-tion steps after pulverization. During mining, crushing and other mechanical operations a significant amount of coal fines (particle size 0.5 - 0.6 mm) is produced. The handling of fine particles is difficult, expensive and.

FIGURE 7-3. Variation of selected coal properties with coal rank. The chemical approach to characterizing coals is to determine the amounts of the principal chemical elements in them. In the jargon of the coal business, this procedure is called the ultimate analysis of coal. Carbon and hydrogen are the principal combustible elements in coal.

The properties of fly ash depend on numerous factors, such as the composition of feed coal, pulverizing and combustion conditions, and conditions of deposition of fly ash. It is difficult to evaluate the relationship between feed coal and fly ash because power plants commonly use blends of coals or coals and other materials (for example, tires or biomass) to fire their boilers.
Jan 26, 2015 This study researched the geochemical origin of coalbed methane (CBM) in three mining areas of the Huaibei coalfield and the distribution of different origin gases. The Rock-Eval data indicate that coal and coaly mudstone in this coalfield are both good gas-source rocks and are within the gas generation window. The large ranges of isotope data (δ13CCH4 = −42.8‰ to −75.5‰ δDCH4.
