Performance analysis of the temporary stockpile reclaimer system in the mining industry using the Overall Throughput Effectiveness (OTE) method

Abstract

The increasing target of coal mining production every year needs to be supported by a reliable performance of the temporary stockpile reclaimer system, in order to ensure a smooth transfer of coal from the temporary stockpile to the main stockpile and achieve the production target. Based on the Overall Equipment Effectiveness calculation, it has been found that the performance of the reclaimer and conveyor system is still below the standard, at 31.04% and 40.26% respectively. Damage to one of the tools in the reclaimer system can cause production to stop and result in wastage and losses. By using the FMEA method and the Six Big Losses, two major potential losses have been identified as the causes of the decline in the reclaimer system performance, namely idling and minor stoppage losses, and equipment failure losses. Efforts to improve the system’s performance include making changes in the height and width of the temporary stockpile to minimize obstacles such as coal material overflow, and regular maintenance should be conducted to ensure optimal system performance.
