Mine support equipment is simple and practical, and can also be recycled. Steel Arch Support is environmentally friendly. The current models are U25, U29 and U36. The U-shaped steel cross section looks like the English letter U. "Also, it will also be in the shape of the Japanese letter "ひ", which is the main type of steel for making tunnel reinforcement Steel Arch Support; it is widely used in mine roadway, support support of mountain tunnel and secondary support of mine roadway.
Tunnel Roof Support Features
1. Tunnel Roof Support is under great pressure, long-lasting support, and easy to install and not easily deformed.
2. Tunnel Roof Support has shrinkage, stable and reliable load carrying capacity compared to other rigid supports, adapting to the load and deformation of soft surrounding rock.
3. The tunnel roof support has a high utilization rate, convenient support for the support, and small maintenance.
4, 25U bracket recycling and recycling rate is high, reducing the use of pit wood, environmental benefits are very obvious. The project is safe and reliable, effectively reducing the occurrence of accidents such as roofing and sheeting, and improving the stability of the mine ventilation system.
The promotion and application research of the project has improved the safe production conditions of the mine, reduced the production cost, and conformed to the policy of replacing wood with steel, which has better environmental protection benefits and social and economic benefits.
