Formation of Coal (Process) Coal is composed of carbon, hydrogen, oxygen, nitrogen, sulphur, moisture, and incombustible mineral matter (, ash). Fluorinated gases are not formed by coal combustion. Coals are formed from the accumulation of vegetable debris in specialized environments. Obtaining coal from the mines is a difficult job.

Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner's progress.

This is a dull black coal with a higher heating value than lignite that is used primarily for generating electricity and for space heating. Most subbituminous reserves are located in Montana, Wyoming, Colorado, New Mexico, Washington and Alaska. Bituminous: Even greater pressure results in the creation of bituminous, or "soft" coal.

Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. This process can be represented by the following flowchart diagram: In this chapter we will look at each of the steps in more detail.

Openpit mining. Some 53% of South Africa's coal is produced from surface mining, via opencast or openpit mines. This is because the coal is less than 60 metres below the surface. Openpit mines use draglines, as well as truck and shovel operations to extract coal. A dragline excavator uses a dragline to pull a bucket by a wire cable.
