Coal formed from dead vegetation that was buried during the Carboniferous period from 360-300 million years ago. Over millions of years, the dead plant matter was subjected to heat, pressure, and time underground, transforming it through various ranks from peat to lignite, sub-bituminous coal, bituminous coal, and finally anthracite coal with the highest carbon content. This coalification process occurred due to the vegetation being buried in an anaerobic environment without oxygen which allowed carbon rings to form.

Fossil Fuel resources for sustainable development
This document provides information about fossil fuels, specifically focusing on coal. It discusses the formation of coal from ancient plant matter over millions of years. Coal is divided into four categories based on carbon content and stage of formation: peat, lignite, bituminous coal, and anthracite. Each stage represents increased pressure and heat over time. The document outlines the characteristics and uses of each coal type. Coking coal is used to make steel, while anthracite burns most efficiently. Coal-bed methane is also sometimes extracted from coal deposits.
Coal 2
This document provides a historical overview of coal use from ancient times to present day. It discusses some of the earliest uses of coal in ancient China and Greece. It then outlines how coal was crucial during the industrial revolution due to its abundant availability. The document also examines early coal mining practices and some of the inventions fueled by coal like early steam engines. Finally, it discusses modern coal mining techniques and coal's main uses today in power generation, as well as ongoing efforts to mitigate coal's environmental impacts.
Coal
This document provides information on various solid fuels including wood, charcoal, peat, and coal. It discusses their origins, compositions, characteristics, and significance. Wood is a domestic fuel that is commonly used in tropical countries and consists mainly of cellulose and lignin. Charcoal is superior to wood and is produced through carbonization or heating wood in the absence of air. Peat represents an early stage in coal formation and varies in composition. Coal is a combustible sedimentary rock formed from the partial decay and burial of plant materials over millions of years. The rank of coals ranges from peat to lignite to anthracite as they gain carbon content and heat value over time. Analysis of coal involves determining its moisture,
Geology
The document provides an overview of geology and various geological concepts through definitions and explanations. It discusses the structure of the Earth, including the crust, mantle, outer core and inner core. It then covers plate tectonics, the geological time scale, minerals, rocks including igneous, sedimentary and metamorphic rocks, faults, folds, coal formation and some key geological terms. Diagrams and images are provided to illustrate geological features and concepts.
Basic information of Coal
Coal is a combustible sedimentary rock formed from fossilized plant matter. It is a non-renewable fossil fuel that is classified based on its carbon and volatile content into peat, lignite, bituminous coal, and anthracite. Coal is used primarily to generate electricity but also in steel production, industrial plants, and manufacturing of chemicals like nylon and plastics. While affordable and abundant, coal is not renewable and burns incompletely, releasing pollutants into the environment.

properties of coal
This document discusses the properties and classification of coal. It describes the three main types of coal - anthracite, bituminous, and lignite - based on their composition and properties like carbon content and volatility. It also discusses the physical and chemical properties of coal that are important for combustion, including heating value, proximate analysis (fixed carbon, volatile matter, moisture, ash), and ultimate analysis (carbon, hydrogen, oxygen, sulfur content). The proper sizing of coal for different firing systems is also covered.
Coal market outlook
This document provides an overview of global coal markets. It discusses different types of coal and their uses. It notes that international trade accounts for a small percentage of overall coal production. The document then examines trends in steam coal and coking coal trade between 1995 and 2012. Subsequent sections provide more details on low rank coal trade, major coal importers and exporters, and dynamics in China, India, and other Asian markets like Japan, South Korea and Taiwan.

Coal is a black sedimentary rock composed primarily of carbon and formed from the accumulation and alteration of prehistoric vegetation over millions of years. It exists as several types and is one of the most widely used solid fuels. Coal forms underground from the decomposition of plant matter and is extracted through surface mining or underground mining. It has properties like heat content, moisture, ash and sulfur content that determine its uses. Coal is burned as a fuel for electricity generation and in various industries like steel production. While a valuable energy source, coal also has disadvantages as its extraction and combustion produce air and water pollution and safety issues in mines.
COAL AND ITS RELATION TO OIL AND GAS
Coal and petroleum are related in their origin from plant matter, but differ in their state and environment of deposition. Both undergo geological processes that change their composition over time through coalification and kerogen formation. Coals can serve as a source rock for natural gas and, depending on their composition and maturity, may generate oil as well. Key indicators of coal rank and maturity include moisture, volatile content, carbon content, and vitrinite reflectance measured microscopically.
Thar coal hurdle&solution
The document summarizes hurdles and solutions for energy generation from Thar coal in Pakistan. It discusses that Thar coal reserves are the 6th largest in the world and could generate 100,000 MW of electricity for 30 years. However, Pakistan currently lacks infrastructure and technology to exploit Thar coal. Key challenges include developing transportation infrastructure to remote Thar, establishing coal gasification technologies, and constructing power transmission lines. Several projects have begun to address these challenges and utilize Thar coal for sustainable energy production.
Less Common Sedimentary Rocks
Chert is a form of quartz that occurs in sedimentary rocks, usually in discontinuous beds or nodules. It can form biologically from siliciclastic rocks or diagenetically from carbonates. Coal forms from plant debris in association with some siliciclastic rocks. It can have banded or non-banded textures reflecting its organic compound content. Coal rank depends on the degree of metamorphism, with increasing rank containing more energy per volume. Evaporites form through chemical precipitation in restricted basins where evaporation exceeds precipitation, leaving behind minerals like gypsum, halite, and sulfates.
Coal mine
This document discusses coal rank, grade, and type. It provides definitions and classifications for these coal properties.
Coal rank refers to the degree of coalification or thermal maturation of coal, ranging from lignite to anthracite. Coal grade is based on purity and ash content. Coal type is distinguished by the type of plant materials that formed the coal. These properties are independent but can vary spatially. Coal is first classified by rank to determine its utilization. Rank is determined through parameters like carbon content, energy value, and maceral composition that change with the coalification process. Coal plies form a basis for sampling and correlation within a coal seam based on variations in lithotype or partings.
Coal classification
Coal can be classified in several ways based on different parameters. Some common classification systems include:
1. Visual classification based on color, structure into categories like lignite, bituminous coal, and anthracite.
2. Proximate analysis classification using parameters like fixed carbon, volatile matter, and fuel ratio to categorize into types.
3. Ultimate analysis classification systems like Regnault-Grüner-Brosquet and Seyler's that classify based on carbon, hydrogen, oxygen, and nitrogen content.
4. National and international standards that use parameters like volatile matter, ash content, calorific value to systematically grade and code different coal types.
