Underground Limestone Mining by Robert M. McKay and Michael J. Bounk The production of limestone aggregate from underground workings requires machinery to illuminate the rock face and to hoist miners into position to clean drill holes and load explosives for blasting the rock. River Products Company, Columbus Junction Mine.
The crew aims for 8-10 shots per day, set off after the first shift leaves the mine around 5 p.m.,” says R.L. Maxwell, Mine Superintendent. Two seismographs measure and record the ground and air vibrations from each blast. The two-hour lag between shifts gives any limestone gases time to dissipate. “The air quality is constantly monitored.

An underground water flow can develop when many rain-fed subsurface drainages join up, or a river can be captured by an open cavity collapse structure (sink hole or doline) and flow underground. This leads to further enlarging and sculpturing of the caves by stone and physical weathering.

Limestone is a sedimentary rock mainly composed of calcium carbonate and calcite formed by marine organisms like coral, shellfish and algae. It holds up to 10% of the total volume of the sedimentary rocks. A pure limestone is white in color, however, with impurities like sand, minerals and clay, limestones are found in different colors too.
