Surface mining is used to obtain mineral ores that are close to Earth's surface. The soil and rocks over the ore are removed by blasting. The trucks take the rocks to factories where the ore will be separated from the rest of the rock. Surface mining includes open-pit mining, quarrying, and strip mining.

23.03.2021Surface mining（ground mining） is suitable for large, low-grade ore deposits. These ore deposits occur below a thin layer of rock or alluvial deposits found in sand and riverbeds. In particular, using this mining method, miners retrieve sand, gravel, stones, coal, iron, and other metals. Surface miner machine（surface mining machines） is essential.
