Coal mining Wikipedia
For example, some western U.S. coal that occur at depths in excess of 200 ft (60 m) are mined by the open pit methods, due to thickness of the seam 60–90 feet (20–25 metres). Coals occurring below 300 ft (90 m) are usually deep mined.
Thermal power station Wikipedia
The coal received at site may be of different sizes. The railway cars are unloaded at site by rotary dumpers or side tilt dumpers to tip over onto conveyor belts below. The coal is generally conveyed to crushers which crush the coal to about 3 ⁄ 4 inch (19 mm) size. The crushed coal is then sent by belt conveyors to a storage pile.
Material-handling equipment Wikipedia
Material handling equipment (MHE) is mechanical equipment used for the movement, storage, control and protection of materials, goods and products throughout the process of manufacturing, distribution, consumption and disposal. The different types of handling equipment can be classified into four major categories: transport equipment
Heavy equipment Wikipedia
Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied, making tasks which could take hundreds of people and weeks of labor without heavy equipment far less intensive in nature. Some equipment uses hydraulic drives as a primary source of motion.
Mining Wikipedia
As the coal recovery cycle continues, the cutter-head is progressively launched into the coal seam for 19.72 feet (6.01 m). Then, the Push-beam Transfer Mechanism (PTM) automatically inserts a 19.72-foot (6.01 m) long rectangular Push-beam (Screw-Conveyor Segment) into the center section of the machine between the Powerhead and the cutter-head.

Cast Mining Methods In Tamil
2019-12-10· When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited.
Coke (fuel) Wikipedia
The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). This process vaporizes or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal-tar.
