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 …

The exploitation requires the removal and disposal of about 50 million cubic metres (Mm 3) of overburden material during the 20-year quarry lifespan. Limestone deposit is covered by a 50–70 m thick layer of soil–clayey sand and clay–which has to be removed by means of excavators/shovels and chain bucket excavator.

The whole process of making any type of lime all begins at the limestone quarry after careful surveys. Most limestone is extracted through blasting. Behind the rock face, holes are drilled to place the explosives. When detonated, the explosion dislodges each time up to 30,000 tonnes of stone. Today's blasting makes use of the latest ...
