Abstract: Ground fissures induced by shallow coal mining significantly damage the ecological environment of mining areas.Timely detection and landfill treatment can prevent secondary hazards such as spontaneous combustion of residual coal and water inrush during rainy seasons.This paper proposes an improved YOLOv8 model for instance segmentation of ground fissures from UAV imagery.Firstly,the backbone of YOLOv8 is replaced with a pyramid vision transformer (PVT) to enhance multi-scale and high-resolution feature learning for dense fissures,improving geometric recognition capabilities.Then,UAV images from the Huangyuchuan Coal Mine in Inner Mongolia were processed to create the HYCdata dataset for model training.Experiments demonstrate that the modified YOLOv8 outperforms the original model,achieving a mAP0.5 of 74.3%,providing an effective solution for automatic segmentation of widespread mining-induced fissures.
