In shaft mining, a shaft is dug straight down into the Earth to access buried deposits. People get in and out of the mine through lifts in the shaft, and additional shafts may be dug to create emergency exits and deal with ventilation needs. In slope mining, a sloping shaft is dug so that people access the mine by moving down an incline.
Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world. Shaft sinking refers to shallow shafts and it is different from a ...

Mining companies are adapting their strategy to address energy costs and regulations requiring a quota of renewable sources from energy generators. Energy use in mining and mineral processing is strongly dependent on the ore quality and ore composition. The energy requirements for openpit mining are different to underground mining.
There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removal. This paper focuses on openpit surface mining, which involves removing ore from a large hole in the ground (sometimes referred to as a borrowpit). 1.
