Optimalizace trhacích prácí na vybraných lomech v souvislosti s časováním odstřelů

Abstract

In this diploma thesis I deal with optimalization of blasting works in chosen quarries with regards on timing. In the preliminary chapters of this diploma thesis I describe chosen quarries in present condition, including current conditions of blasting works. Then I describe technique, which is used in chosen quarries on blasting works. I also describe explosives and detonators, which are used on chosen quarries. In several chapters I also describe timing of blasting works and what is influence between timing and fragmentation or muck pile shape. In the last part of diploma thesis I suggest changes of blasting works for chosen quarries, which can reduce the cost of future blasting works. Diploma work presents knowledge gained within project PL.3.22/2.3.00/12.03351 – sustainability program „Education of specialists in the field of post-mining care in the Polish-Czech border region. “
