Underground monitoring and communication systems are diverse and complex, and various monitoring and communication cables, especially optical fiber cables, are ubiquitous. With the mining of fully mechanized working faces and the subsequent withdrawal of the entire working face, a large number of various communication lines need to be withdrawn and raised to the surface. After being raised, the communication lines vary in length and variety. To reduce production costs in coal mines, reusable lines need to be neatly reeled and stored. This is especially true for optical fiber cables, which often reach several hundred meters in length when withdrawn. Automatic reeling devices are often used to save time and effort when reeling.
