Limestone deposits occur in a variety of landforms. Some are in the form of a hill. Some are plain thick slabs; some are fragmented with substantial interstitial impurities. The first step is to drill holes, fill them with appropriate explosives and blast them so as to loosen the rock. Loosened rock is collected by shovels and loaded into dumpers.
