Minerals and mineral products are the backbone of most industries. Coal is an organic sediment consisting of a complex mixture of substances. It has a lot of commercial and industrial applications. It is an energy giving nonrenewable source of energy. Mining of coal is one of the oldest industrial operation.

Chapter 18 Refrigeration Plant and Mine Air Conditioning Systems Malcolm J. McPherson 18 3 can no longer remain in the liquid phase but burst free to form a vapour or gas (Section ). If, however, the applied pressure is raised to a higher value, then additional heat is required to vaporize the liquid.

the mining operation involves cyclical, step bystep mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof. Roomandpillar mining generally is limited to depths of about 1,000 feet because at greater

Ø The goal of the planning and design of underground coal mining operations is a strategy for designing an integrated mineral exploitation system that will ensure that coal is extracted and prepared at a desired market specification, at a minimum unit cost, within acknowledged safety, health, social, legal and regulatory constraints. Ø

"Strip mining" is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden). It is most commonly used to mine coal and

ABB in mining and mineral processing industry. Creating value and visibility from mine to port and from plant to enterprise. We start with the best people, engineering expertise and over a century of knowledge and knowhow of electrification and process control in mines. Our team then provides integrated solutions and services.

In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners. Therefore, runofmine (ROM) coal—the coal that comes directly from a mine—has impurities associated with it.
