Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a mining tunnel supporting device. Background Art

[0002] Mining tunnels, also known as mine tunnels or roadways, are various passages drilled between the surface and the ore body. They are mainly used for ore transportation, ventilation, drainage, pedestrians, and various necessary preparatory projects for the new excavation of ore for metallurgical equipment.

During mining operations, small rocks may fall from the unsupported tunnel roof, compromising the safety of equipment and workers inside the tunnel. Furthermore, mining tunnel support devices are typically bulky, making them difficult to transport and install within narrow tunnels. Therefore, we propose a mining tunnel support device to address these issues. Utility Model Content
