Coal mining - Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions. 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 …
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 …

Coal preparation plants incorporate a variety of separation processes that operate in relatively independent parallel circuits. The identification of optimum cutpoints for each circuit that globally maximize plant performance have historically involved the use of mathematical simulation routines. Unfortunately, these routines require detailed ...
The dilatation of coal has been primarily measured by two different standard procedures – the Ruhr Dilatometer and the Audibert-Arnu Dilatometer. Both of the methods were very similar having the same basic apparatus and heating rate but used different initial masses of coal arising from the method of pencil preparation.
Effective beneficiation of fine coal; i.e., coal sized below 1 mm, either by means of deashing or dewatering, or a combination of both, is mainly dependent upon the following factors: (a) favourable coal selling price and a growth situation in coal demand; (b) improved performance and favourable cost of fine coal preparation equipment;
