Abstract

Sensitivity analysis of lignite ultimate pit size and its parameters on change of lignite base price The influence of lignite base price on the size of ultimate pit (lignite supply) and decrease of lignite quality (decrease of calorific value and increase of sulphur and ash content) has been analyzed. The consequence of these changes is the relative decrease of real price of averaged lignite and changes of non-discounted pit cash flows. The influence of lignite base price on strip ratio has also been calculated. The ultimate pit from Lerchs-Grossmann optimization as well as phases from parameterization process conducted in NPVScheduler program has bee used for calculations. The base of analysis was the quality model of “Szczerców” deposit used for creation of value model with usage of price formula taking into account lignite quality parameters.
