Some limestones are also aquifers, that is, they are rock units that can yield water to wells.
A Limestone is surface mined through open pit quarries or hillside cuts, or horizontally by tunneling under the overlaying surface rock. Quarrying is the most common method used, because it is an easier and cheaper method for removing shallow deposits. Underground operations are used when the overlaying surface rock is too thick.
