Underground Limestone Mining: The basic operations in underground mining are drilling, blasting, loading and hauling, scaling and roof bolting. Drilling equipment includes horizontal drills and downhole track drills. This equipment is generally quite different from that used for surface mining and results in much smaller blast holes and a lower ...
Sand, gravel, and crushed rock quarries employ standard surface-mining techniques.Crushed stone is used for concrete aggregate, for road building, and, in the case of limestone, as flux in blast furnaces and for chemical applications.The quarrying technique consists of drilling and blasting to fragment the rock. A large number of charges are fired at one time, producing up to 20,000 tons of ...

The Rexton Project will initially involve surface quarries and, in the future, an underground mine. Our exploration program in the region has located limestone of both suitable quality and quantity, and we are now securing the rights to the land, as well as proceeding with applications for the required permits.
Underground mining began, using a room and pillar approach. In 1984 Marengo, LLC acquired the quarry and continued to mine limestone. Two years later, the quarry was first leased as a storage facility to the US federal government for grain storage. In 1995, the company began modernizing the quarry for use as warehouse space.
