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.
