Their operational reliability directly impacts the coordinated efficiency of mining, transportation, and other processes. With the rapid development of intelligent mine construction, traditional methods of manually breaking, fastening, and splicing belts are no longer suitable for the efficient and safe production needs of modern mines. Especially with the widespread adoption of rapid tunneling technology, the frequency of conveyor belt splicing operations has increased significantly, yet current technologies still face challenges such as low efficiency and high safety risks.
