- Mining is classified by the method needed to reach the coal seam. When the coal is found close to the Earth's crust and taking away the overlying layers of material is not too expensive, surface mining is used to remove the top layers of materials and expose the coal.If coal is found in layers far from the surface, underground mining is the preferred technique.Vertical or slanted holes (shafts) are cut down to the mining area underground for ventilation for the workers and for transporting the miners, equipment, and coal.ining is classified by the method needed to reach the coal seam. When the coal is found close to the Earth's crust and taking away the overlying layers of material is not too expensive, surface mining is used to remove the top layers of materials and expose the coal.

Why coal is usually found in layers??? EXPERT ANSWER. Coal if formed when dead animals and plants got buried inside the layer of Earth. The layers increase form time to time and more dead plants and animals get buried in the layers.Therefore, coal is found in layers.For example, let us consider the layers of sandwich, on the first bread we apply the toppings and cover it another slice. Then some more topping is added to second slice and is covered by third slide.XPERT ANSWER. Coal if formed when dead animals and plants got buried inside the layer of Earth. The layers increase form time to time and more dead plants and animals get buried in the layers.

Coal The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.oal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was about 7.25 billion tonnes in 2010 (7.99 billion short tons) and is expected to increase 48% to 9.05 billion tonnes (9.98 billion short tons) by 2030.

How does coal form? please help? More than two hundred million years ago,huge trees grew in the warm,humid swamps that covered vast regions of the world.Coal began to form in these swampy forests about 350 million years ago,during the carboniferous period.Decaying plants were buried under layers of mud.As heat and pressure increased ,plant remains slowly converted into coal.There are three main grades of coal - lignite,bituminous coal and anthracite.

"America is  the ""Saudi Arabia"" of Coal" America is the Saudi Arabia of Coal Plant fossils of West Virginia are examples of the fossil flora that comprise the vast coal reserves that are typical in the Eastern United States. Coal is formed from ancient plant material accumulating over long periods of time in swamp conditions so devoid of oxygen that bacteria could not exist to cause decay. Being composed almost entirerly of plant fossils, coal is in effect concentrated sunlight, and is one of our most important fossil fuels. The United States as a whole has more recoverable coal resources than any other country on the planet-- over 262 billion tons-- enough to last over 200 years!

- Coal is a fossil fuel created from the remains of plants that lived and died about 100 to 400 million years ago when parts of the earth were covered with huge swampy forests. Coal is classified as a nonrenewable energy source because it takes millions of years to form. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. All living plants store energy from the sun through a process known as photosynthesis. After the plants die, this energy is released as the plants decay.

Coal Sub bituminous coal is a lignite that has been subjected to an increased level of organic metamorphism. This metamorphism has driven off some of the oxygen and hydrogen in the coal. That loss produces coal with a higher carbon content (71 to 77% on a dry ash-free basis).oal is also used as a power source for factories. There it is used to heat steam and the steam is used to drive mechanical devices. A few decades ago most coal was used for space heating. Some coal is still used that way but other fuels and coal-produced electricity are now used instead.

- Sulfur is a yellowish substance that exists in tiny amounts in coal. In some coals found in Ohio, Pennsylvania, West Virginia and other eastern states, sulfur makes up from 3 to 10 percent of the weight of coal.imestone can be made to absorb sulfur gases under the right conditions much like a sponge absorbs water. In most scrubbers, limestone (or another similar material called lime) is mixed with water and sprayed into the coal combustion gases (called flue gases).

How Did We Get All This Coal? Each coal bed may be inches to feet thick, formed by the accumulation and compacting of thick piles of dead plant material. It has been estimated that, if all the vegetation living on the earth’s surface today were converted to coal, it would amount to only a small fraction—perhaps 3 percent—of the earth’s coal reserves.2.

- Found with petroleum in many locations is a gas called natural gas. Natural gas is composed mostly of methane, CH. Coal, petroleum, and natural gas are the fossil fuels. The energy they contain is used when these fuels are burned to supply heat for a variety of uses.Over 90% of all the energy that man uses comes from these fossil fuels.Coal is often burned directly to produce heat.Or, coal can be processed to produce other useful fuels and products. When coal is heated in the absence of air, three useful materials are produced, a gas, a liquid, and a solid.ound with petroleum in many locations is a gas called natural gas. Natural gas is composed mostly of methane, CH. Coal, petroleum, and natural gas are the fossil fuels. The energy they contain is used when these fuels are burned to supply heat for a variety of uses.

What is Coal Used For? Lignite-Lignite is the softest coal with high moisture content, which is often referred to as the brown coal. It is the lowest rank of coal that is mainly used as a fuel for steam-electric power generation.Sub-bituminous-It is softer than bituminous coal, but relatively harder than lignite.oal is a fossil fuel, which has found a wide range of applications and uses in the modern world. Coal was believed to form during the carboniferous age (about 298 to 358.9 million years ago), from the dead plant and organic matter that accumulated at the bottom of the water bodies.

- INTRODUCTION. 1  Coal is abundant in the U.S., is relatively inexpensive, and is an excellent source of energy and byproduct raw materials. 2  Because humans have used coal for centuries, much is known about it. 3  Some of the problems that accompany the mining and use of coal are well known. Acid mine drainage results when coal beds and surrounding strata containing medium to high amounts of sulfur, in the form of compounds known as sulfides, are disrupted by mining, thereby exposing the sulfides to air and water.

How Coal Works As time went by, the plant matter evolved from moist and low-carbon peat, to coal, which is much higher in energy and carbon content. Coal itself has a wide variation in properties, so it is categorized into 4 ranks—lignite, sub-bituminous, bituminous, and anthracite—in order of increasing carbon and energy content.
