Basic Introduction
The Underground Mine Bolting Jumbo is an underground mine bolting support machine used for roof and rib bolting and cable bolting in coal mines, metal mines, tunnels and other underground projects. It integrates drilling, hole cleaning, bolt installation and grouting/anchoring into one operation, replacing manual labor and greatly improving support efficiency and safety.
Model Advantages
⭐As a piece of underground mining equipment, The Underground Mine Bolting Jumbo is specially designed for mines with low-height roadways and can perform roof and rib support simultaneously, greatly shortening support time and improving efficiency. It features a reasonable and compact structure, flexible operation and convenient control, making it the preferred equipment for fast, efficient and mechanized roadway excavation and support.
⭐This machine adopts a dual-boom design, which significantly improves working efficiency. Remote control operation is optional to maximize operational safety. A variety of models are available to meet construction requirements of roadways with different widths and ensure easy operation for workers.
