摘　　要：为研究矿石溜放对溜井井壁围岩的磨损破坏规律,保证溜井安全连续稳定生产,需要对溜井井壁进行检测。为实现溜井直径大、有浮石、粉尘多、湿度高和无光源等特殊条件下的井壁安全检测,研制了垂直溜井全景扫描成像装置。该装置采用4台高分辨率工业摄像机目标跟踪技术、4个高照度LED冷光灯照明技术、千兆网数据传输技术、旋转编码器井深定位技术等,实现对井壁全断面、无缝式扫描;通过组合式电缆与自锁绞盘提升系统实现装置提升;通过图像筛选与拼接处理,得到溜井井壁全景图。将该装置应用于矿山溜井进行井壁检测试验,采集到的井壁图像清晰直观,为溜井井壁磨损破坏规律研究、制定和实施溜井检修方案提供了直接依据。试验结果表明,该装置能适用于复杂条件垂直溜井的井壁检测。In order to study the wearing pattern of the ore-pass wall, and ensure the continuously safe and stable production of the ore-pass, it is necessary to monitor the ore-pass wall. The diameter of the ore-pass is large. It is dusty, damp and lightless in the ore-pass, and there are unstable stones on the ore-pass wall. To safely monitor the ore-pass wall, a vertical ore-pass panoramic scanning imaging device is developed. The device realizes full-face high-resolution and seamless scanning of ore-pass wall with 4 cameras for target tracking, Gigabit Ethernet for data transmitting, high illumination of 4 LEDs for lighting, rotary encoder for depth locating, and combination cable and self-lock capstan for lifting. Screening and stitching the scanned images, the full-face images of the ore-pass come out. The device is applied to a monitoring experiment of the ore-pass wall at a mine. The image data of the experiment visually and clearly reflect the damage degree of the ore-pass wall. That is the basis to study the wearing pattern, and to design and fulfill the scheme of maintaining and repairing ore-pass. Experimental result shows that the device is suit for monitoring complex vertical ore-passes wall.
