Underground stone mining operations in the United States commonly utilize a room-and-pillar mine layout with drill-and-blast production methodology for the development of the reserve. Within the Midwest and Eastern regions, thick and flat-lying limestone formations lend themselves to the utilization of multiple level mining layouts.

This paper reviews the results of the changes made at Maysville, recent horizontal stress measurements conducted at the Black River mine, and the recent modifications to the Black River mine design. Roof fall statistics at both operations are used to compare the distinctly different mine layouts used at the two mines.

SURFACE LIMESTONE MINING: All over the world, limestone is generally mined from a quarry or through open-pit mining. This method is the easiest way to remove limestone without causing much destruction. In surface mining or open-pit mining, the topsoil and overburden covering the mineral are removed.
