Conducting blasting in an open pit environment is an essential step in the technology of rock processing. The subsequent stages of transporting and processing the resulting rock fragments critically depend on the quality of the blast. As a result, the control of blast quality in real time is necessary during blasting in the open pit. This paper compares the quality of detection and segmentation of rocks obtained after blasting using the YOLO model family. A series of neural network training experiments were conducted and compared using the metrics precision, recall, average precision, and inference time per image. Based on experimental results, it is shown that the updated YOLOv8X model performs better for both detection and segmentation tasks. For the object detection task, YOLOv8X shows an average precision of 76%. This outperforms the YOLOv7X model by 1% on Average precision and the YOLOv5X model by 5%. In the segmentation task, the YOLOv8X model outperforms the YOLOv7X model by 5% on Average precision, and the YOLOv5X model by 7%.
