— 2.3 Information About Drilling–Blasting Activities of the Study Field. Production at the study field is carried out using drilling and blasting methods. The diameter of the drill holes is 89 mm in the quarry. Standart ANFO and emulsion explosive is used as the primary explosive in the quarry, with electric detonators as the ignition systems.
The strictness of the result of an excavation, whether mechanical or by means of explosives, is naturally conditioned by its objective and, therefore, by the type of technique applied to achieve it. To attain the best results in terms of rock breakage, and with respect to the final profile, it is important to evaluate the specific excavation energy and its …

— This project conducted in order to analyses the optimization of drilling and blasting parameters to influence achievement of good fragmentation at Songwe II Limestone quarry. The main objective of this …
Blasting is the most widely used method to excavate limestone for cement production as the rock is usually too hard to be ripped or dozed. This involves the drilling of holes in the rock, placing a predetermined charge of explosive in each hole and detonating it. The result is a pile of broken rock which then has to be removed to the cement plant.
