Other major coal users are the cement, food, paper, automobile, textile and plastic industries. Another important industrial use is to provide coke for iron and steel industries. Bituminous coal derivatives, or byproducts can be changed into many different chemicals form which we can make paint, nylon, aspirin and many other items.
Search form. Search. Coal. What is coal? Where is coal What tends to vary much more than the assessed level of the resource the potentially accessible coal in the ground is the level classified as proved recoverable reserves. Resource: The amount of coal that may be present in a deposit or coalfield. This does not take into account
An openpit coal mine is a huge hole in the ground with terraces along which earthmoving vehicles excavate seams. It looks a bit like a sports stadium. The largest openpit mines are several kilometers long and hundreds of meters deep. First of all, the layer of earth overburden above the first coal seam has to be removed.
This gas is also produced as coal forms. Coal, as a solid, mostly sits where it was formed. Eventually, if the rocks above it are eroded so that it is exposed at the Earths surface, the coal itself may be eroded away, and either eaten by bacteria, or buried in new rocks. And, occasionally, a natural forest fire or a lightning strike

Coal forms when dead plant material builds up and up to form peat, which is the first step. This is compacted between layers of sedimentary rock, forming a rock called lignite. Then this is
Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbonbased material approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coalbearing rock units appeared about 290360 million years ago, at a time known as the Carboniferous or quot;coalbearingquot; Period.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a ''pit'', and
#0183;#32;Of course, after a star supernovas and forms gold, the precious metal has to travel to Earth in some way. By studying ancient rock samples with highprecision instruments, scientists have found evidence that accessible gold, or the gold that is technologically and economically feasible to reach on the surface of the planet, arrived via asteroids when the earth was still fairly young.
#0183;#32;Coal is a particular variety of kerogen, that forms from remains of superior plants (trees, ferns). It is a kerogen that has the characteristic of being dominant in the sediment instead of being a very a small fraction of it. The first stage of the sedimentation process leads to peat.
#0183;#32;Coal is a solid fossil fuel Fossil fuels are nonrenewable . They took a very long time to form and we are using them up faster than they can be replaced once they have all
#0183;#32;Many people believe that diamonds are formed from the metamorphism of coal. That idea continues to be the quot;how diamonds formquot; story in many science classrooms. Coal has rarely if ever played a role in the formation of diamonds. In fact, most diamonds that
#0183;#32;Coal, oil and hydrocarbons in general are made from living organisms that have been broken down from intense heat and pressure millions of years ago. Marine organisms like algae and plants died over the ocean floor. Then, they were compacted into the ground and heated in an environment without oxygen.
When vegetation in the carboniferous era fell on the ground, it rotted (decomposed) to form peat. As sediments kept accumulating over the peat, the peat hardened to form coal.
#0183;#32;In order for oil to form, the mixture must achieve a temperature that geologists refer to as the quot;oil window.quot; Otherwise, it remains in its kerogen state. Over time, the oil travels upward through pores in the rock. Some seeps out onto the Earth''s surface, but most remains stuck in barriers. Underground traps of oil are called reservoirs.
