Arch supports are widely used in mine tunnels and are a type of support equipment. The shape of the arch bracket is generally U-shaped steel material. It has shrinkability, stable and reliable bearing capacity with other rigid brackets, strong support strength, and can be used repeatedly.
Steel arch supports are mainly used for secondary support of mine tunnels and mine tunnels through mountain tunnels. It has the characteristics of U-shaped steel bracket withstanding large pressure, long support time, and easy installation and deformation. The steel arch bracket has a high collection and reuse rate, which reduces the use of pit logs, and the environmental protection benefit is obvious. The project is safe and reliable, effectively reducing the occurrence of accidents such as roof fall and film gangs, and improving the stability of the mine ventilation system.
During the use of the steel arch support, it can be repaired and re-used, which overcomes a series of shortcomings of waste of resources. It has high repair efficiency, small loss of U-shaped steel strength, environmental protection, and promotes the secondary use of resources.
