基于机器视觉的两阶段电法监测突水实时预警

Real-time early warning of water inrush via machine-vision-enabled two-stage electrical monitoring

  • 摘要: 深部采掘工作面处于高地应力、高水压等复杂地质环境,使得突水灾害问题变得愈发严峻。随着人工智能技术的快速发展以及智慧矿山建设的不断推进,深度学习和计算机视觉在矿山安全监测领域逐渐被推广应用,为降低突水灾害风险提供了新路径。针对深部矿井的突水实时预警需求,创新性地将深度学习、机器视觉与电法监测相结合,提出了一种基于机器视觉的两阶段电法监测突水实时预警技术。监测过程分为2个先后阶段,即视觉识别阶段与分析决策阶段。在视觉识别阶段中,使用训练好的轻量化深度学习模型YOLO11s快速精准识别图像中的低阻区域并获取其位置坐标。随后将位置坐标传入分析决策阶段,在分析决策阶段中,使用OpenCV-HSV颜色过滤算法从个数、面积占比、颜色深度3个维度分析已识别的低阻区域的灾变特征,综合判断低阻区域是否为风险区域,并采用自动决策机制触发多级预警。结果表明:YOLO11s模型能够准确地评估水源是否会导致突水问题,实现了自动决策触发多级预警,克服了其他监测手段在实时监测、灾变分析、早期预警等方面存在的局限;YOLO11s模型在识别低阻区任务中mAP达到90.2%,模型平均推理速度每帧34.6 ms,模型平均处理速率为 28 FPS。相较于YOLOv8、YOLOv5、Fast R-CNN具有更强的性能,能够实现对低阻区的精准、快速识别;系统使用的OpenCV-HSV颜色过滤算法对单帧图片的平均分析决策时间为7 ms,实现了对突水的实时预警。

     

    Abstract: The deep mining working face is characterized by high in-situ stress and high water pressure, making water inrush hazards increasingly severe. With the rapid development of artificial intelligence and the continuous advancement of smart mining construction, deep learning and computer vision have been widely applied in mine safety monitoring, providing new approaches for mitigating water inrush risks. Aiming at the need for real-time water inrush early warning in deep mines, this study innovatively integrates deep learning, machine vision, and electrical monitoring, proposing a real-time two-stage electrical monitoring method based on machine vision. The monitoring process consists of two consecutive stages: the visual recognition stage and the analysis and decision-making stage. In the visual recognition stage, the lightweight deep learning model YOLO11s is used to rapidly and accurately identify low-resistivity regions in electrical images and obtain their spatial coordinates. These coordinates are then passed into the analysis and decision-making stage, where an OpenCV-HSV color filtering algorithm analyzes the identified low-resistivity regions from three aspects—quantity, area ratio, and color depth—to comprehensively determine whether the regions pose potential water inrush risks, triggering multi-level warning responses through an automatic decision mechanism. Results show that the YOLO11s model can accurately assess whether water sources may cause water inrush hazards and automatically trigger multi-level warnings, overcoming the limitations of other monitoring methods in real-time detection, disaster evolution analysis, and early warning. The YOLO11s model achieved a mean Average Precision (mAP) of 90.2%, with an average inference time of 34.6 ms per frame and an average processing rate of 28 frames per second (FPS), outperforming YOLOv8, YOLOv5, and Fast R-CNN in detection accuracy and speed. The OpenCV-HSV color filtering algorithm required only 7 ms per image for analysis and decision-making, realizing real-time early warning of water inrush hazards.
