Strip Mining - an overview ScienceDirect Topics

In strip mining, the overburden is mined and moved by the same equipment: draglines or continuous excavators. The movement of overburden in strip mining is called the casting process. The operating sequence for each pit includes drilling and blasting, followed by overburden casting, then coal removal.

What is Strip Mining? (with pictures) - Info Bloom

24-01-2021  Strip mining is a type of surface mining which involves the removal of a thin layer of material known as an “overburden” to access buried deposits of useful minerals. This type of mining is only effective in areas where mineral deposits are very close to the surface, making it feasible to quickly and easily remove the overburden to get to them. Classically, strip mining is used to mine tar sand
