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.
"overburden" (rock above the coal seam), and "interburden" (rock between coal seams).
