List of equipment used in opencast coal mining are: 1. Bulldozer 2. Craper 3. Ripper 4. Tractor Shovel 5. Dipper Shovel 6. Stripper Shovel 7. Pull Shovel or Hoe 8. Dumpers or Tippers 9. Drag Line 10. Road Grader 11. Rock Drills. Opencast mining is the oldest method of excavating minerals but the mining operations have been mechanised by the use of heavy earth moving .
When coal is available in the large square kilometer, the large piece of equipment is used. Machineries with bucket wheel, trucks are used to excavate the coal . The open pit or surface mining uses the land only for the temporary use, later rehabilitations of the lands are done after the extraction of the coal. The surface techniques can be classified into contour strip mining, area strip ...

Track Hopper is made from reinforced cement concrete(RCC) hopper,steel gratings which covering the RCC hopper and two parallel rail track at the center of the hopper. Wagon Tippler .
· Coal extraction takes many different forms for both underground and surface. Underground mining. Underground mining in turn is classified according to how access to the coal is accomplished. Thus, an underground mine can be a 'drift' mine, where access is bored horizontally from the surface to the deposit, such as the side of a mountain; a 'slope' mine .

what equipments are used in a coal mine site. Coal mine An area of land and all structures, facilities, machinery, tools, equipment, shafts, slopes, tunnels, excavations, and other property, real or personal, placed upon, under, or above the surface of such land by any person, used in extracting coal from its natural deposits in the earth by any means or method, and the work .
· 27 Reserved percolation:Reserved percolation: In this case the extraction is done through the general percolation procedure. At the last, the evaporation is done under reduced pressure in equipment like a Climbing evaporator to the consistency of a soft extract (semi solid) such that all the water is removed. This is then dissolved in the ...
· The presence of ash in coal also greatly reduces the coal utility because of its deleterious effect on the boiler parts and gasifiion equipment. Solvent extraction (organorefining) techniques produce Super Clean Coal (SCC) or Ultra Clean Coal (UCC) with almost zero ash content. The utilization of the SCC in the Integrated Gasifiion ...

Early coal extraction was smallscale, the coal lying either on the surface, or very close to it. Typical methods for extraction included drift mining and bell well as drift mines, small scale shaft mining was used. This took the form of a bell pit, the extraction working outward from a central shaft, or a technique called room and pillar in which 'rooms' of coal were extracted with ...
