Abstract: 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.

Key words: panoramic scanning imaging, underground mine, ore-pass wall monitoring, device development, device experiment
