Drilling Exploration assessments of the blasting provide information about the type of rock structure that is appearing in the deepest layers, this allows the executor of the blasting to make objective judgments that allow him to include adjustments to his blasting design considering the changes in the structure of the rock mass.
The specialist responsible for this activity must have a broad knowledge about the action of the explosives in the massif during the blasting, without that knowledge, the blasting becomes a random process of trial and error.
The extraction of aggregates and other natural building materials is carried out through two modes of exploitation: the underground exploitation mode and the open-air mode. Although we can speak of two types of quarries, underground and open-pit, the latter have obtained the greatest diffusion. The choice of mode of exploitation depends among other factors on the depth to which the deposit is located in the rock mass and its physical and geological characteristics.
