Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburdenis relatively thin or the
ADVERTISEMENTS: 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 
Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called open cast) mine. Additionally coal seam thickness and geology are factors in selection of a mining method. The most economical method of coal extraction for surface mines is the electric shovel or drag line. The most economical form of underground mining is the long wall, which is a shear blade that runs along sections of the coal seam. Many coals extracted from both surface and underground mines requir
Open pit machinery can also be used for other purposes such as civil construction, whereas underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of machines required.

Coal is mined either by surface methods (open-cut or open-cast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

May 22, 2020 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. Open cast 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.

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

Open pit mining also called open cut mining or open cast mining is a surface mining technique used to extract rocks and minerals. It requires large-scale equipment, including shovels and drills. Motor graders also play a role, maintaining haulage roads so that both equipment and mined material can be transported to and from the mines.
Blast casting is a high-efficiency technique applied in surface mines for overburden removal and results in stripping cost savings. According to ballistic theory and center-of-mass frame basic movement principles, key factors influencing blast casting effect were analyzed, which include bench height and mining panel width, inclined angle of blast holes, explosive unit consumption (EUC), delay
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
