| Abstract | During the design phase of any mining operation, it is very important to ensure ore production with specific quality characteristics, which are mainly established by the standards of each consumer. While high and medium frequency quality variations of the ore, can usually be compensated using homogenization and/or mixing techniques, and appropriate short-term production planning, low frequency variations can be reduced by appropriate mine planning and design to ensure constant production quality throughout the whole operation, which may last a few decades. In this study, the influence of two strategic development options (scenarios) on the long-term quality variation of lignite extracted from the South Field mine at the Ptolemais-Amydeon basin, are examined. In both scenarios the continuous mining method is applied. In the first scenario, the field is divided in 10 sectors and pivot operations are applied for 2 sectors and parallel operations for the remaining 8 sectors. In the second scenario the field is divided in 11 sectors and pivot operations are applied on all sectors. Simulation results showed that the second scenario is better for reducing the long-term variability of lignite quality. This chapter examines the influence of two strategic development options on the long-term quality variation of lignite extracted from the South Field mine at the Ptolemais-Amydeon basin. The majority of the lignite mined at the South Field Mine is fed to the nearby power plant of Agios Dimitrios, with a nominal output of 1585 MW. The quality of the mined lignite varies significantly and does not always meet the power station specifications. Quality variation is closely related to the formation characteristics of each deposit and the mining conditions, and can be described as short-term variation or high frequency, middle-term variation or medium frequency and long-term variation or low frequency. Mine planning has to determine the number of sectors to divide the deposit, the pattern to apply to each sector as well as the sequence of mining each sector. Simulation results showed that the second scenario is better for reducing the long-term variability of lignite quality. |
