Surface limestone mining. All over the world, the limestones are generally mined from a quarry or the open pit mining. It is the easiest way to remove the limestone without causing much destruction. In surface mining or open pit mining, the top soil and the overburden covering the mineral is removed. Then by the process of drilling the rocks or ...

the Mine Safety and Health Administration, in consultation with the operator. Controlling groundwater is another important aspect of mining operations. Water is usually present at some depth below the surface; and once encountered by mining, open crevices, fractures, and solutional voids in the limestone may produce variable flows of groundwater.

The room-and-pillar mining method is used extensively in underground limestone mines in the Eastern and Midwestern U.S. The rock mass is typically a near-horizontal, bedded deposit at relatively shallow depth. A survey of 34 mines was conducted in which data on roof spans, rock mass properties and support

rock in a mining environment to ensure safety of the workforce and . serviceability of the mine openings (MOSHAB, 1997). Ground control in limestone mines can be complex because the entries are fairly wide and have large heights. Rocks falling from a high roof have signiicant injury potential. During a survey of roof stability
