Ekonomické zhodnocení vlivu technologických změn při primárním drcení kamene na technologickou dopravu v kamenolomu Jakubčovice nad Odrou

Abstract

The theoretical part of the thesis informs the reader about the approach to handling the topic and about the basic problems of open-pit mining. Further, quarry in Jakubčovice nad Odrou is characterised and the company EUROVIA Jakubčovice, s.r.o. is introduced. The theoretical part also informs about the method of stone mining used, explains the principles of drilling, blasting, loading, technological transport, treatment and expedition of aggregate. In a further part of the thesis, a research describes the current state of primary stone crushing and technological transport and creates an alternative state of technological transport carried out by the company. It defines two variants of solution. The thesis evaluates technological changes of both variants, compares them with the current state and suggests further possibilities for the solution of the problem.
