The Coal Mine is the first mine players are introduced to. It can be unlocked from completing Into the Depths It features a gray, rock-lined layout reinforced with large wooden support beams to prevent collapse. The tunnels are lit with torches and lanterns, and coal deposits can be found throughout the hallways.
