Types of Coal Mining

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 openpit method, is the ideal technique when ...

Coal Production

Coal Production

Coal production and mining activities have negatively impacted our environment and human health resulting thereby in poor quality of air and water, land degradation, loss of flora and fauna, etc. Mine spoils have completely changed the landscape (Gajić et al., 2018; Maiti, 2012). Physicochemical analysis of mine waste and tailings show majorly sandy coarse textures, low content of clay ...

What are the types of coal?

What are the types of coal?

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalifiion," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are:

History of Coke

History of Coke

As coal and coke production grew steadily at Walston, the officers of the RPCI formulated plans for the opening of another mew mining and coking plant in Young Township, two miles from Punxsutawney. The mines at the site appropriately named, "Adrian" in honor of chief investor Adrian Iselin, made its first shipment in January, 1887. At the time a local newspaper reported that "the coke works ...
