This paper illustrates, by means of the case study of the most important lignite deposit in Northern Greece, the lignite recovery in multi-seam or “zebra” type lignite deposits. It discusses the difficulties encountered in most efficiently producing lignite from this type of sequence, characterized by the multiple interchanges of lignite layers and thin sterile intercalations consisting mainly of clays, marls and sands. The knowledge of the geometry and the quality characteristics of the recoverable lignite ar...
