Types of Coal Mining - FEECO International Inc.

When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the open-pit method, is the ideal technique when ...

Coal – Types, Uses and Formation

Each type has different proportions of carbon and thus, have different uses. Peat - This type of coal has less than 40% to 50% of carbon, while the remaining is moisture. This makes it difficult for us to ignite and cannot be easily used. Lignite - This type of coal has 40% - 55% carbon content, which implies that moisture content is lesser ...
