In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the

Coal Preparation an overview ScienceDirect Topics

Modern coal preparation plants can be as complex and sophisticated as processing facilities used in the chemical industries. However, for simplicity, plant flowsheets can be generically represented by a series of sequential unit operations for sizing, cleaning, and dewatering (Fig. 1). This sequence of operations, which is commonly called a

Chapter 7 COAL Pennsylvania State University

Coal is an organic rock (as opposed to most other rocks in the earth's crust, such as clays and sandstone, which are inorganic); it contains mostly carbon (C), but it also has hydrogen (H), oxygen (O), sulfur (S) and nitrogen (N), as well as some inorganic constituents (minerals) and water (H2O).

Refined coal Wikipedia

Refined coal is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned.
