The three main types of surface coal mining are strip mining, openpit mining, and mountaintop removal (MTR) mining Surface Mining: Strip Mining Strip mining is used where coal seams are located very near the surface and can be removed in massive layers, or strips Overburden is usually removed with explosives and towed away with some of the largest vehicles ever made Dump trucksThe coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock This process takes millions of years Types, or “ranks,” of coal are determined by carbon contentWhat are the different types of coal? | American
