Limestone extraction SOLANCIS

Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. Before beginning the quarrying process, a resource analysis is made. This study investigates the existence and quantity of stone at the site and also the ...
