[0002] Coal mine short-arm interval mining currently has the industry pain point of backward equipment and low mining efficiency. As the roadheader continues to mine, the subsequent equipment cannot follow up in time. The roadheader needs to be stopped and the scraper or belt conveyor of the subsequent supporting equipment needs to be extended before the material can be transported. The continuous transportation of materials cannot be achieved, which takes up a lot of manpower, material resources and time, affecting work efficiency.

[0003] At present, the materials excavated by underground tunnel boring machines in my country are transported to the tail of the tunnel boring machine through the scraper conveyor equipped with the tunnel boring machine, and then transported to the main belt by the underground loader, or transferred to the main belt by a scraper or belt. As the tunnel boring machine continues to move forward, the distance from the main belt gradually becomes farther, resulting in the loader frequently and repeatedly unloading materials, or the transfer scraper conveyor and transfer belt conveyor being shut down to extend the construction, which takes up a lot of manpower and material resources and affects work efficiency.
