Coal is a sedimentary rock, formed over millions of years from the remains of decayed plants. It is mainly composed of carbon, with small amounts of hydrogen, oxygen, sulfur, and other elements. Coal is classified into four main types: anthracite, bituminous, subbituminous, and lignite.
The highest level of coal is anthracite, which has a carbon content of over 87%. Bituminous coal has a carbon content of 77-87%, while subbituminous coal has a carbon content of 60-70%. Lignite, the lowest level of coal, has a carbon content of less than 60%.

Conclusion
The y level for coal is the vertical distance from the surface of the coal seam to the bottom of the coal seam. The y level is an important factor in determining the quality of the coal and the amount of coal that can be extracted from the seam.
The y level can also be used to determine the depth of the coal seam.
