The procedure is applied in all working quarries of Iktinos Hellas SA and is based on Maptek Vulcan Quarry Modeller, a mine planning package adapted for quarrying.
The difference between a mine and a quarry should be noted. In case of a mine, the operations are carried out under the ground at great depth. In case of quarry, the operations are carried out at ground level in an exposed condition. Methods of Quarrying. The methods of quarrying the stone may be five: Digging or excavating. Wedging. Heating
methods. Further, the topic of the estimation of commercial marble block size distrib ution from measurements on oriented drill coring techniques is briefly discussed. A n example case of a white dolomitic marble quarry is used to demonstrate these methods.
What Happens at a Marble Quarry? At the quarry, it can take months before any marble is able to be extracted from the earth. But once it is, the process can finally begin.
