Productivity in mining operations is highly dependent on the efficiency of heavy equipment such as excavators. Conventional methods for measuring excavator cycle time are often manual and inefficient. This study aims to develop a real-time cycle time detection system using the You Only Look Once (YOLO) object detection algorithm. Video data from excavator operations were annotated to train the YOLO model, which was then integrated into a user-friendly application using OpenCV. The system achieved a mean Average Precision (mAP) of 94.2% and operated at 30 Frames Per Second (FPS), enabling accurate and real-time detection of excavator activities. The system enhanced monitoring efficiency and operational productivity. Its implementation in mining environments demonstrates the potential for automated cycle time analysis to support equipment management, improve safety, and reduce operational delays.
