Underground mining Underground mining involves creating tunnels from the surface into the mineral seam, which can be hundreds of metres below the surface. These tunnels are used to transport machinery that extracts the mineral. Underground mining accounts for 60% of world coal production, but it is less common in Australia, making up around 35% of raw coal production.
