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.
