Coal is one of Minecraft's most useful resources as it provides light in the sometimes dark and scary Overworld.
The item can be mined and gathered from coal ore blocks found throughout the Overworld.
The following information pertains to the current Minecraft release, Update 1.16.5. Coal's spawning mechanics will change in Update 1.17.
Coal ore spawns very commonly from levels 0-137. It will spawn in veins as small as one ore to as large as 37 ore. On average, 307 ore spawns per chunk, which is quite a large amount.
Coal can be mined with any pickaxe, including Wooden. It can also be dropped by Wither Skeletons.
