Využívání nové technologie roznětu při trhacích pracech v organizaci Kámen a písek.

Abstract

The technology of nonelectrical initiation is not so new, how it seems on the first look. Even though some explosives managers still stand up for its larger exploitation. Maybe it is just aversion to try something new, something, which is not usual for them. I have directed my bachelor’s work to summary of my experiences with this system of initiation, with its advantages (for example higher safety of work, the defence against unwanted initiation which is clear from the deep base of this system, possibilities of smaller fragmentation of the blast, reduction of seismic effects of the blasting), but also with its disadvantages (higher price, impossibility of checking blasting net , possibility of failure and other). In the work I summarize experiences got by study of technical literature, attendance on specialist seminaries and schooling, but first of all making of few hundreds bench blasting, which we made with my colleague and consultant of this work in quarries of the company KÁMEN A PÍSEK spol. s r. o. Český Krumlov.
