Wpływ optymalizacji kopalń odkrywkowych na rozwiązanie modelu bilateralnego monopolu: kopalnia & elektrownia w długim okresie

Abstract

THE INFLUENCE OF LIGNITE OPENCAST MINE OPTIMISATION ON SOLUTION OF BILATERAL MONOPOLY MODEL OF LIGNITE MINE & POWER PLANT IN LONG RUN The classical and modified solution of bilateral monopoly for the system of opencast mine and power plant has been presented both using graphical and analytical methods. Determined through pit optimization and parameterization the influence of lignite base price on lignite supply in long run and on volatility of nested pits’ parameters (e.g. overburden to coal ratio) and quality of lignite contained in them (calorific value, sulphur and ash content) has been used to find optimal solution for bilateral monopoly: mine & power plant. It was shown that in contrary to the classical solution the modified one is determined not only in area of quantity of intermediate product (lignite) but also in its price. The hypothetical solution for the pit placed on the “Szczerców” deposit has been shown and discussed
