Because all the minerals piled on top of it and pressed down on it so they all squish on top on it
Coal is found in various places like underground. It is mainly found in the crust but very rarely found in the mantel.
Coal deposits are commonly referred to as coal seams or coal beds. These are layers of coal that are found buried beneath the Earth's surface.
Coal is usually found in layers because it forms from the remains of ancient plants that accumulated over time in swamps and marshes. As new layers of plant material build up, the older layers are compressed and transformed into coal through heat and pressure. This process repeats over millions of years, leading to the formation of multiple layers of coal.
Coal is typically found in sedimentary rock layers within the Earth's crust, often formed from compressed plant material over millions of years. It is commonly mined from coal beds or seams that are buried beneath the surface. These coal deposits are found in different regions around the world where the conditions for coal formation were present.
Coal is found underground because it is formed from the remains of plants that lived in swamps millions of years ago. Over time, the plants decomposed and were buried by layers of sediment, leading to the formation of coal deposits deep underground.

it is a sedimentary rock which means it has been transformed from a different type of rock over millions of years :)
Coal is formed from the remains of plants that lived in swamps and marshes millions of years ago. These organic materials were buried under layers of sediment and compressed over time. Coal deposits are typically found in areas where these conditions existed, such as former swamps and wetlands.
The layers of coal are called peat, lignite, subbituminous, bituminous caol, and anthracite. Peat being the most inexpensive and anthracite being the most valuable. Most coal in use is bituminous. Another answer: A layer of coal in a mine is called a coal seam.
Please see related link, showing the coal producing countries and maps. The maps show where coal is found in the US. If you need to know where coal is found in other countries, you will probably find this using a Google search under the country name and the word coal. US, Russia and China are large coal producers.
Coal is typically found in sedimentary rocks such as sandstone, shale, and limestone. Petroleum is found in sedimentary rocks as well, usually in porous reservoir rocks such as sandstone or limestone that are capped by impermeable rock layers like shale or mudstone.
