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 adequate working height for the equipment and miners
What Is Coal Preparation Coal preparation is the removal of undesirable material from the Run of Mine ROM coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities Through coal preparation a uniform product is achieved
The low and high separation densities of 6 0 5 mm fine coal were much higher than those of 50 6mm coarse coal at the same operating conditions Moreover the middlings obtained in compound dry
The fine coal with water in this particle range is also called coarse slime GN Horizontal Screen Scroll Centrifuge can remove the moisture in the fine coal or coarse slime by a high centrifugal force and the coarse slime is discharged due to the differential speed between the scraper and the screen basket
Selection between the options would be based on expected over capacity needs raw coal distribution problems and costs of pumps screens and other ancillary equipment For this example eight 711 mm cyclones will be selected The volumetric yield of feed slurry to the underflow stream can be determined using the expression
It is indicated that the CCS has a more advanced separation performance for the coarse coal than the traditional cyclones of 90° and 110° For the middle size fractions 0 5–0 25 mm and 0 25–0 125 mm the ash content of the clean coal is similar to that of 110° and slightly lower than that of 120°

Ash of clean coal reduces less about 5 10 than one of raw coal Though coal below 6mm can hardly separates in separator some information has shown there is some fine coal in feed coal to improve separation effect of rough size coal When content of below 6mm coal is about 20 ash of above 6mm coal is reduced to lowest
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
