Nov 04, 2011· 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

Coal Mining and Processing | Energy Trends Insider

Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.

Digging deeper: Mining methods explained | Anglo American

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

What are the types of coal? USGS

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

Jul 07, 2020· Coal mining, extraction of coal deposits from the surface of Earth from underground. Coal has been used since the Bronze Age, 3,000 to 4,000 years ago, and was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries.

Surface mining | Britannica

This process is called surface mining and was widely used as a method for extracting coal in the Ohio River valley and in England. This technique is also used for mining phosphate deposits, gypsum, gravel, limestone, copper, iron, and other minerals.

Mar 23, 2018· Very different actually. There are many ways of mining coal. They all have the same basic concept, so I'll focus on one. Mountaintop removal is used for all sorts of mining purposes, but is frequently used to extract coal in Appalachia. Miners literally use explosives to blow off the tops of mountains to reveal deposits of ores, which they extract, and then process by usually filtering them

The Mining Process | Introduction | underground COAL

The Mining Process. Once a mining lease has been awarded to an operator, exploration (i.e. evaluation of the resource) takes place, followed by a planning and development process before excavation or mining begins. this type of mining will not give rise to subsidence at the surface In some mines or parts of mines first workings is the only

How Underground Mining Works | HowStuffWorks

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
