| Description | Open pit optimisation is not too frequently used for lignite deposits, especially in Europe, where there are almost no new lignite mines. The new design work of a planned lignite pit in Poland provides an opportunity for successful implementation the optimisation methods since the beginning. The paper presents a study of the lignite pit design with the use of the newest available optimisation tools. First, the pricing formula has been applied to calculate the in-situ lignite price. Basing upon the quality block model of the large lignite deposit, the ultimate pit has been obtained with the use of a Lerchs-Grossmann algorithm. As a result of mine blocks optimal sequencing, the optimal pushbacks and the long term schedule have been obtained with the use of a NPV Scheduler package. This chapter presents a study of the lignite pit design with the use of the newest available optimisation tools. Basing upon the quality block model of the large lignite deposit, the ultimate pit has been obtained with the use of a Lerchs-Grossmann algorithm. The data of the large lignite deposit with the estimated resources of nearly 1 billion tons has been chosen for the project aiming the following topics: ultimate pit with price sensitivity analysis, pushbacks generation and long term schedule. The selected quality parameters: calorific value, ash and sulphur content have been interpolated within geological zones using the inverse power of distance method and thus the quality block model has been obtained. To compute the price of each cell in the block model, the price formula established for lignite by the Mining Committee of the Polish Academy of Sciences has been applied.
