Support arch is a kind of passive support equipment for coal mine support. Support arch has high tensile strength, high compressive strength, and good toughness, high supporting force, strong supporting strength, and can be used multiple times. It is widely used in mine roadways, especially in deep complex roadways and soft coal seam roadways.
After the Support arch is installed, you need to check the verticality and torsion of the bracket. If it exceeds the allowable error range specified in the quality standard, adjust it. According to the vertical line placed in the middle of the top beam and the horizontal distance between the two column feet, You can know whether the support is vertical or not. According to whether the line between the center line of the tunnel and the two columns is vertical, you can know whether the support is skewed.
The Support arch has the characteristics of being easy to install and not easy to deform. In addition, the support arch section has a high utilization rate, and the support is easy to maintain and less expensive. The stent recycling rate is high, and the environmental benefits of reducing the use of pit wood are obvious. China Coal Group welcomes new and old customers to come and buy.
