Coal is a black solid or sedimentary rock, which is combustible in nature. It has a large amount of carbon in it almost 50% of its weight. The formation of coal takes a long long time. The first coalbearing rock is said to have appeared about 350 million years ago. This period was known as the carboniferous period or the "coalbearing ...

Under these conditions, the carbon compounds in the buried organic matter can undergo chemical reactions, leading to the formation of fossil fuels like coal, oil, and natural gas. This process is known as diagenesis. Carbonization: In certain conditions, such as oxygendepleted environments or peat bogs, organic matter can undergo carbonization ...

As the layers of sediment continued to accumulate over the peat, the intense pressure exerted by the weight of the overlying rocks, combined with the heat generated by the Earth's internal processes, caused the peat to undergo physical and chemical changes. This process, known as coalification, gradually transforms the peat into coal.

The biosphere (all biological activity such as plants, animals, and their remains) also plays a vital role in sedimentary processes. All organic matter eventually decomposes, releasing vital nutrients (such as N, Ca, C) into the soil and sea. Both coal and oil are formed by the interaction of buried organic matter with sedimentary processes.

Mining Coal. Coal is extracted by two principal methods, of which there are many variants: surface mining or subsurface mining. Surface mining uses large machines to remove the soil and layers of rock known as overburden to expose coal seams that are close to the Earth's surface (figure (PageIndex{4})).Strip mining is a type of surface mining in which overburden is sequentially removed ...

There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]
