Coal mining by open-cut methods. A dragline is used to remove overburden from a gently dipping coal seam, placing it in spoil piles on the up-dip side (left). A pattern of blast holes has been drilled into the overburden on the right of the image. The coal is removed by a power shovel and placed into trucks for haulage from the mine.

What is open pit mining . Open pit mines are those mining operations that take place on the surface, unlike the underground mines. This is possible when the reservoir sprouts on the surface or at a very small depth. It began to be realized in the middle of the XVI century and it is used all over the world.

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Surface mining began in the mid-16th century [dubious ...

Choosing a mining method. The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, and social factors.

Auger mining uses large-diameter drills mounted on m obile equipment to bore into a coal seam. Holes are horizontally drilled at regular intervals to depths of as much as 1,000 feet. As the cutting

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. This equipment can include the following: Draglines which ...

Mining is extremely dangerous. If you don't know what you're doing or how to use your equipment, you can easily get hurt. The best way to stay safe and prepare for a career in mining is to educate yourself on the different types of equipment you will be working with daily. Underground vs. Surface Mining Equipment Different mining sites require their own unique sets of equipment.

Open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.
