      Coal - Coal - Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. As peat formation and coalification proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and hydroaromatic. Modern coal-quality data and geologic field observations are interpreted in terms of the coal geology in a small area near Pocahontas, Va. Detailed chemical analyses and physical-property determinations of 12 channel-coal samples (reported on whole-coal and laboratory ash basis) indicate that the coals are mostly of high coking quality, low.

      The system of interrelationship of indices developed previously has been refined from the results of chemical and petrographic investigations. The influence of the degree of reduction on the hydrogen content in the sintering components of coals has been determined more accurately. Coal deposit, Coal Creek District Gunnison County, Colo.: reserves, coking properties, and petrographic and chemical characteristics.

        Utah, constituent state of the United States of America; it became the 45th member of the union on January 4, It is bordered by Idaho to the north, Wyoming to the northeast, Colorado to the east, Arizona to the south, and Nevada to the west. The capital is Salt Lake City. The paper is mainly a review of published data on the chemical nature of the banded contituents of coal seams. Consideration is given to ultimate and proximate composition and to the nature of the products obtained by oxidation, reduction, and thermal decomposition. In general, the petrographic components of a coal from a given seam differ in chemical composition, but the differences are not.

The purpose of this study is to explore how the geochemical and petrographic components of coal may impact its physical properties and how these correlate with a history of reportable dynamic failure in coal mines. Dynamic failure events, also termed bumps, bounces, or bursts, are the explosive failures of rock in a mining : Heather Lawson.

Petrography is a branch of petrology that focuses on detailed descriptions of e who studies petrography is called a mineral content and the textural relationships within the rock are described in detail.

The classification of rocks is based on the information acquired during the petrographic raphic descriptions start with the field notes at the. This investigation presents the findings of an initial study into whether the grinding resistance of coal can be reduced with microwave pretreatment without significantly altering the fundamental properties of the coal.

A U.K. steam coal was sieved into seven size fractions and then treated with high-electric-field-strength microwave energy for a short duration to investigate how the grinding.

Accurate petrographic analysis is an important tool to evaluate bituminous coals and coal blends and their ability to produce blast furnace coke. Coal petrography is performed by examining polished specimens of minus 20 mesh prepared coal. Rank is determined by measuring the percent reflectance of the maceral vitrinite.

Under fluorescence mode these are found to be rich in liptinite macerals, in particular the liptodetrinite and resinite. The essence of the petrographic approach to the study of coal composition is the idea that coal is composed macerals, which each have a distinct set of physical and chemical properties that contol the behavior of coal.

Sixteen sandstone samples were tested to determine the PM parameters and then thin sections from those samples were used to measure the petrographic parameters. development of coal classification are described in this section. The properties of coal (chemical, physical, mechanical, and petrographic) are used as classification parameters.

Some of the properties of coal that are used in its evaluation for end use processes appear in a number of classification systems. There are two kinds of classification.

T he history of coal mining in Utah is one of outside economic domination which has created a distinctive ethnic mix in the central southeastern area of predominantly Mormon Utah.

The area was first controlled by major railroads, and, since World War I, increasingly by international energy companies.

However, Utah's coal industry began under the aegis of the LDS Church, which reserved valuable.
