Overall Equipment Effectiveness (OEE) has been used since last over two decades as a measure of performance in manufacturing industries. Unfortunately, enough, application of OEE in mining and excavation industry has not been duly adopted. In this paper an effort has been made to identify the OEE for performance evaluation of Bucket based Excavating, Loading and Transport (BELT) equipment. The conceptual model of OEE, as used in the manufacturing industries, has been revised to adapt to the BELT equipment. The revised and adapted model considered the operational time, speed and bucket capacity utilization losses as the key OEE components for evaluating the performance of BELT equipment. To illustrate the efficacy of the devised model on real-time basis, a case study was undertaken on the biggest single bucket excavating equipment – the dragline, in a large surface coal mine. One-year data was collected in order to evaluate the proposed OEE model.

Podejście oparte o całościową ocenę efektywności używane jest od ponad dwóch dekad w analizach skuteczności działania urządzeń w przemyśle wytwórczym. Niestety podejście to nie zostało szeroko przyjęte w przemyśle górniczym. W pracy tej podjęto próbę dokonania całościowej oceny efektywności pracy układu złożonego ze sprzętu do urabiania, załadunku (koparki) oraz transportu. Model koncepcyjny podejścia całościowej oceny stosowany dotychczas w przemyśle wytwórczym został zaadaptowany by uwzględniać specyfikę systemów urabiania, ładowania i transportu. Odpowiednio zmodyfikowany model uwzględnia czas pracy układu, tempo pracy, spadek ładowności koparki i spowodowane w ten sposób straty, umożliwiając dokonanie całościowej oceny wydajności pracy systemu. Poprawność opracowanego modelu działającego w czasie rzeczywistym zbadano na przykładzie systemu do urabiania, załadunku i transportu wykorzystywanego w dużej kopalni odkrywkowej węgla. Do oceny poprawności modelu wykorzystano zebrane dane obejmujące cały rok pracy urządzeń.
