Typical Method in Underground Mining: In underground mining, the thickness of the quality seam will determine the number of lifts or layers that can be removed at one time: For thicknesses of up to 10 meters, a single heading will remove all the limestone from the seam. Thicker seams will require multiple lifts to remove all of the quality stone.

Quarries are made when big deposits of commercially helpful minerals or rock are found close to the Earth''s surface. Quarrying is a type of mining and is also called as open pit mining or strip mining.
