Etymology
Origin of mining
First recorded in 1250–1300; Middle English: “undermining (walls in an attack)”; mine 2 + -ing 1
Explanation
The process of removing something valuable from underground is mining. In order for coal to be used as fuel, it has to first be extracted from sedimentary rock through mining. Mining is used to extract minerals, gemstones, oil, gas, and any other materials that are useful or valuable enough to make the process worthwhile. Digging up substances from the earth is always tedious and sometimes dangerous. Coal mining is notoriously unhealthy for its workers, and surface mining involves blasting rocks with explosives to extract precious metals. You can think of mining as a kind of underground tunneling, from the verb mine, "to dig a tunnel."
