Návrh na optimalizaci vrtných prací při lomovém dobývání

Abstract

This paper focuses on drilling operations optimization for quarrying works. The introductory part aims to describe particular drilling rings used for quarrying. Major attention is paid to submersible hammer drill and its practical usage. Principal part of the paper discusses the exploitation of a new mathematic method “Simulated cooling”, leading to the optimal dislocation of lips on boring crowns. The concluding section is dedicated to assessment of the proposed solution from the viewpoint of technical and economic benefits for quarrying works.
