The two main methods used for coal extraction are surface mining and underground mining. The methods used to extract coal depend on the geology of the coal deposits. According to Energy Trends Insider, the amount of coal produced by one miner in one hour has more than tripled since 1978 because of improvements in mining technology and the growth in surface mining. The majority of the world's
