to study the different characteristics of coal washing by Float-and-Sink test. A design of a washing plant has been made with the help of data collected from this test. The data collected simply shows the washing characteristics of washing of coal from which the coal can be varied from easy-to-wash to difficult-to-wash coal.
Coal mining - 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 adequate working height for ...

coal seam and leaving behind 'pillars' of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam – although this coal can sometimes be recovered at a later stage. This can be achieved in what is known as 'retreat mining', where coal is mined from the pillars as workers retreat. The roof is
