Key Project Information
Cleaning Works on the Head and Tail Pulleys of the Belt Conveyor Branches in the Standard Equipment at Kyrio Pedio Mine
Brief Description of the Scope
The project involves cleaning works on the head and tail pulleys of the belt conveyor branches in the standard equipment at Kyrio Pedio Mine for the year 2014.
The objective is to ensure seamless operation of the belt conveyors and extension of their service life. Furthermore, cleaning also aims to eliminate point charges and restore alignment, to avoid increased wear and tear of the rubber lining and drive rollers.
Belt Conveyor Cleaning & Maintenance
Continuous-operation opencast mining is applied extensively to lignite deposits of great horizontal spread in the Prefectures of Kozani and Florina. A primary feature of this method is the continuous excavation, transport and dumping equipment used.
To ensure the proper operation of the belt conveyors, they were serviced and cleaned of residual material deposits, and their alignment was checked and restored. Cleaning is accomplished with the use of special devices, metal and/or plastic scrapers.

History of the Mine
Operations at this mine began in 1957, when the Kyrio Pedio [Main Field] was opened, and were extended to Voreio Pedio, Pedio Komanou, and Pedio Mavropigis. The mine at Mavropigi was initially opened in 2001, with conventional equipment, while in 2003 the first bucket excavators were installed, to secure supply for the SES Ptolemaida, due to the exhaustion of the deposits in the Voreio Pedio and Pedio Komanou, which it replaced.
