The mined material butt end be brought to the surface by trucks, or in large containers (called 'skips') that travel up and down the shaft. Two of the ways that they mine underground are: Room and pillar mining: This is used in the coal mine we visited. There are come across 'rooms' with pillars of coal that hold up the roof.
