Modernizace a rozšíření technologické linky na kamenolomu Bělice

Abstract

This diploma thesis deals with upgrading and extending the technological line of the quarry Bělice for the production of ground rock. Modifications of the line are designed on the basis of laboratory physical-mechanical testing of the stone from the quarry in comparison with the ground rock produced by the present line. The aim of the upgrading and extending the line is to favourably affect the shape index of ground rock grains in the production and thus to increase demand for it by companies producing concrete mixtures and covered gravel. The shape index of the grains of the constituents for those applications is set by relevant regulations. Appropriate modification of the production line can yield improvement of the parameters of the shape index. The introduction describes the quarry, the deposit character, the mining method and the present line. Several finding from the present quarry and production line operation is mentioned.
