methods and brief explanations of the techniques of room-and-pillar mining, sublevel stoping, cut-and-fill, longwall mining, sublevel caving, and block caving. The second section describes underground mining equipment, with particular focus on excavation machinery such as boomheaders, coal cutters, continuous miners and shearers. 1.

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.

Advantages and disadvantages of open pit mining. Open pit mining is profitable when the deposit is not very deep or when the terrain is sandy or delicate, so that underground mining is not possible. Labor costs are lower, both in excavation and transportation, and allow the use of large machinery .

Underground mining, where miners tunnel beneath the Earth's surface to extract mineral deposits, is rarer than open-pit mining. In 2014, it made up about 5% of all American mining operations — and has less of an impact on the surface. However, this doesn't mean that underground mining doesn't have an effect on the environment.

The first task in open pit mining is to remove the top soil, subsoil, and overburden rocks in sequence. The overburden is dumped separately. It can be reverted for replacement in reverse order. The next stage is to open the mineralized ground as the first slot, known as a box cut. The slot is then expanded to form a bench system.
