ANALYSIS OF REASONS FOR UNPLANNED STOPPAGES OF MACHINES IN THE EXAMPLE OF THE LONGWALL SHEARER

Abstract

Production enterprises mainly focus on activities concerning tangible resources. In recent years, however, this focus has shifted increasingly towards intangible resources such as knowledge as a key resource. Knowledge plays a crucial role in building an enterprise’s competitive advantage, including that of mining entities involved in coal extraction. This article presents results of research into the causes of unplanned stoppages in the operation of longwall shearers. An examination of the parameters of the longwall shearer operation reveals an oversight in recording the causes of many unplanned machinery stoppages. Using informatics tools, the authors determine the reasons for most stoppages. The knowledge gained in this research has practical significance in providing a basis for implementing actions to limit the number of stoppages and improve the effectiveness of the machinery.
