in surface and underground mines. However, the total number of injuries per one million employee-hours for underground US coal mines in the last decade is three to four times higher than for surface mines. The difference between the injury rates per one million tons of coal production further demonstrates this point underground mining is less

The largest underground mine is Kiirunavaara Mine in Kiruna, Sweden. With 450 kilometres (280 mi) of roads, 40 million tonnes of annually produced ore, and a depth of 1,270 metres (4,170 ft), it is also one of the most modern underground mines.

ABB takes underground mining to a new level

The Kiruna mine is the world’s largest underground iron ore mine and its 11 ABB mine hoists make it the largest hoisting plant in the world. ABB is currently upgrading the four underground hoists and has supplied a seventh surface hoist to enable LKAB to boost production capacity by 25 percent to 33 million tons of crushed ore a year.

Mining Underground mining Britannica

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of

The many advantages of underground mining

Underground production is estimated to be 44.1 million tons of ore averaging 0.55 percent nickel and 0.16 percent copper. Enhancing its opencast operations with an underground mining could potentially increase the Kun-Manie mine site by at least 19 percent.
