Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

The effect of peak acceleration and particle size on water ...

To keep the size consistent, both coal and iron ore were sieved to below 11.2 mm. Then, both materials were divided into three size ranges to investigate the effect of particle size on the moisture migration. These groups were 0–0.18 mm, 0.18–1 mm and 1–11.2 mm.
