Some Issues in Limestone Mining. Limestone is most often mined from a quarry. However, underground limestone . mines are found at places in the central and eastern United States, especially in and near cities. Underground mining of lime - stone has some advantages over surface quarrying and will probably increase in the future.
Limestone and dolostone are quarried from open pits and underground mines. Drilling and blasting releases the stone from the outcrop and provides first-order breakage. The rubble is then hauled to a crushing facility where the stone is further crushed, screen-sorted into size classes, and stored.
In the South African limestone and dolomite industry, there are currently 24 producers and 43 quarries. Eleven limestone producers supply 80% of the South African market. Dolomite and limestone are used commercially in unprocessed, ground, air-separated, precipitated and calcined forms. Cementitious products are derived from a blend of limestone,

Limestone, dolomite, and marble - the carbonate rocks - are the principal karst-forming rocks. Karst is a type of topography that is formed on limestone, gypsum, and other rocks by dissolution that is characterized by sinkholes, caves, and underground drainage regions. Karst areas constitute about 10 percent of the land surface of the world (ﬁ g.
