Návrh na změnu parametrů trhacích prací v lomu Bílčice za účelem dosažení menší fragmentace

Abstract

The diploma thesis deals with a proposal of changing blasting operation in order to achieve lower fragmentation of the mined material in the Bílčice quarry. The opening chapter decribes the properties of the bed in a chosen area of the quarry including the parameters of the mined material and the technological procedure of bench blasting. A description of the current results of the blasting operation is included in the thesis. The main focus of the thesis is on the project of bench blasting which allows a decrease of mined material fragmentation. In the conclusion the suggested solution is being evaluated from the point of view of technical, economical and ecological contribution to mining in the given locality of the Bílčice quarry.
