Coal mining methods

Apr 03, 2017Coal mining methods. Surface MiningSurface Mining is used for about 40% of coal production in the world. Ore bodies close to the surface at depths less than approximately 180 ft (50 m), are usually surface mined. Coal that occurs at depth of 180 to 300 ft (50 to 100m) is usually deep mined but, surface mining techniques can be used. a).

Plant Optimization Technologies

The program's primary emphasis is to support the development of advanced technologies that use coal with near-zero emissions. To provide this support, the program identifies scientific and technological needs and develops a basic understanding of the underlying chemical and physical processes that, unless resolved, could create a technological barrier to these new coal-based concepts.

Coal quality course : ALS

Control of coal quality requires a good understanding of how the various stages of the coal chain are linked to subsequent stages i.e. coal exploration programs are linked to coal mining and coal preparation plant performance. Similarly, coal mining is linked to coal preparation plant performance which is in turn linked to coal sales.

Technology in Coal Mining Industry

Till the 1950th coal mining companies applied two methods of exploration - surface mining techniques or underground ones. Surface mining techniques are popular and are widely used in the USA mines since 1970s. This method is useful when coal deposits lie near the surface and can be easily extracted.

Advanced Drilling Techniques Horizontal Drilling. Horizontal drilling starts with a vertical well that turns horizontal within the reservoir rock in order to expose more open hole to the oil. These horizontal legs can be over a mile long; the longer the exposure length, the more oil and natural gas is drained and the faster it can flow.

Technology in Coal Mining Industry

In the 1950s, a new underground mining method appeared in Europe. It is called a 'longwall mining' method that applies laser technology. Today, it is widely used by coal mining companies in the world. From this moment the coal exploration, extraction and delivery to the market have become secure, effective, clean and not harmful for the environment.
