Abstract :

This study aims to analyze the performance of coal unloading equipment apron feeder 1-4 which the unloading target wasn’t achieved. One of the main aspects of mining activities is the transportation of coal and unloading of coal. Meanwhile, unloading is the activity of moving material or coal from the previous transportation to a place or tool on an ongoing basis. In the supply chain, the railway system has an important role in the distribution of goods because the train has a short travel time with a large capacity. The results of analysis of the existing situation showed that the unloading target was not achieved due to the high obstacles of apron feeder 1-4 and the slow unloading on the apron feeder. The results of root cause analysis obtained the roots of the problem were the modification of a new train carriage which caused the length of the train carriage wasn’t suitable with apron feeder and there was no safety device in some parts, because of that we have modified the dimensions of apron feeders 1-4 which was adjusted to the length of the new train carriage with a target of decreasing slow unloading. With the decreasing of the unloading obstacles, the unloading achievement has increased.
