ABSTRACT
Of the mining of brown coal using surface mining methods, a concept of large opencast operations by means of production units of TC2 series (excavators KU 800 and K 2000, long-distance belt conveyors with 1600 and 2200 mm belt widths and stackers ZPD 800, ZP 5500 and ZP 6000) and TC3 series (excavator K10 000, long-distance belt conveyor with 2200 mm belt width and stacker ZP 10 000) is characteristic. When serious large-scale excavator accidents happen, enormous operational losses occur. It is necessary to deal with the interruption of mining operations, replacement of the largescale excavator and renewal of production capacities. For the localities where an incident has happened, a number of possibilities of transferring inactive large-scale excavators, either from the mining company itself or from other companies, always exist. The large-scale excavator moves under its own power in an assembled state or is transferred in a disassembled state and then is again assembled on an assembly site. A specific alternative is the temporary or permanent replacement with bath technology. In the article, authors are concerned with the economic analysis of replacement of a large-scale excavator KU 800.5/K65 from the Bilina opencast mine that burnt out by fire and was totally destroyed [1,7].
