Open-pits are sometimes called "quarries" when they are producing building materials and dimension stones. Open mines are dug on benches that are between four and sixty meters in size but it depends on the size of the machinery used to excavate them. How do you relate the open pit mining issue to Heidegger's concept on modern technology as

Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.
