is similar to open-pit mining. It is used to collect mineral deposits that are close to the surface in horizontal beds. In strip mining, the overburden is removed, and then lots of small holes are drilled in the rock just over the ore. Explosives are then placed in the holes to break up the rock so that it is easier to find the mineral.

What is Electrical Discharge Machining and how does it work?

Electrical discharge machining produces surfaces with a fine finish and high precision. Moreover, EDM allows users to machine hardened workpieces. Whereas other machining techniques need to be executed before the workpiece is hardened with heat treatment, electrical discharge machining can be applied on the hardened material as well.
