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;Coal mining, extraction of coal deposits from the surface of Earth from underground. Coal has been used since the Bronze Age, 3,000 to 4,000 years ago, and was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries.
Among them, Surface mining method is applied for producing coal of about nearly 40% in the world. The coal deposits are found on the surface of the earth and make the mining easier for the coalminers. The various types of coal mining are contour, mountaintop removal and strip mining.
When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the openpit method, is the ideal technique when

There are two types of room and pillar miningconventional mining and continuous mining. Conventional mining is the oldest method and accounts for only about 12% of underground coal output. In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars.
The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or ranks, of coal are determined by carbon content.
The various methods of mining a coal seam can be classified under two headings, surface . There are three types of portal adopted in coal mining as drift, slope, and shaft. 10.

Here are the Types of Underground Mining and Their Applications. The method to be used for underground mining depends on the concentration of ore, strength of the surrounding rock, and the various risks involved. ScienceStruck explains what these methods are, with the
#0183;#32;The first published, reference to the mining of coal in India dates back to the year 1774 in the Raniganj Coal Field. Coal mining methods can be broadly divided into two types viz. Surface Mining Methods and Underground Mining Method. The Indian coal industry is the worlds third largest in terms of production and fourth largest in terms of reserves.
