Subject aims expressed by acquired skills and competences

The aim is to teach students to design technology for blasting rock when disconnecting stamping horizontal underground works of a small cross section. Within the scope of become familiar with an assortment of resources blasting equipment, igniter charges, the theory and releasing their own technology. Finally proposes a technological process of blasting work with the determination of basic parameters of the blast.
