    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.
