Aggregate Quarrying Process. Stone quarrying is the multistage process by which rock is extracted from the ground and crushed to produce aggregate which is then screened into the sizes required for immediate use or for further processing such as coating with .
· Surface extraction is ''quarrying'' although metalliferous surface mines are often referred to as ''openpits'' and surface coal mines as ''opencast''. At the present time, the lower cost of surface mining dictates that almost all aggregates are produced by quarrying. The methods and equipment employed in quarrying rock or excavating sands and gravels are similar to those used in ...
