The extraction of coal is one of the activities involved in mining operations, where drilling, blasting, milling, crushing, sizing, and screening of minerals are performed. At PT. MAL, Indonesia, this extraction activity involves in-pit processing, such as the sizing of coal using a fixed screen. This study aims to analyze the technical sectors regarding the use of fixed screens in coal production activities. This is carried out to reduce the production time and costs, as productivity is expected to increase and completely meet market demands. The challenges involved in the use of fixed screens influenced the availability value of coal. In this case, the use of availability (UA) and effective utilization (EU) values of the utilized excavator were insufficient. These conditions were due to the observation of many challenges in the coal extraction activities. The challenges also affected the performance and production of the excavator, where the solution emphasized the redesign of the fixed screen through the modification of several parameters, such as the angle of repose and screen capacity.
