Summary
The subject defines the basic concepts in the field of technical blasting. The main objective is to explain the design of different type of blasting works, the partial aim is direct to compile knowledge on the use of technical blasting for various purposes. It is also referred to the analysis of the damaging effects of blasting focusing on the seismic loading of buildings (methodology according Czech Technical Standard CSN 73 0040).

Summary of topics:
Technical blasting
Disintegration theory of hard materials
The calculation principle of concentrated charges
Principle of breaking and calculation of cylindrical charges
Basic characteristics of individual cumulative blasting
Designing of cumulative blasting
Geometric parameters of the charge system
Initiator and inflammation of bench blasting and areal blasting
Projection of coyote-hole and combined blasting
Cumulative blasting technology
Secondary blasting
Shaking blasting
Blasting with controlled discard of material
Blasting on buildings
Blasting on one-sided rock excavation
Blasting for rock cuts
Blasting in construction pits
Blasting for destruction
Damaging effects of explosion
Learning Outcomes of the Course Unit
The subject follows the subject named „Blasting Operation and Rock Disintegration“. The content is deepening the knowledge for designing of geometric and explosive parameters of various types of technical blasting. Students will be able to design the parameters of technical blasting separately, based on a specific assignment. The assignment may include a requirement for proper rock disintegration, blasting with discard of material, non-excavating blasting, shaking or destructive blasting. It is assumed the ability of student to design the most appropriate type of blasting. The student will be able to predict the value of the damaging effects of the planned blasting and to interpret the result of seismic measurements in view of possible damage on buildings.
The subject forms a suitable pre-stage for subsequent study to obtain the authorization of explosive manager, respectively technical heads of explosive works.
