Coal is mined by two methods: surface or 'opencast' mining or underground or 'deep' mining.
The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface mining is more common.
