The best stress state of the U-shaped steel arch support is that the back wall is filled and compacted to make it evenly compressed. When the pressure value of the surrounding rock used on the U-shaped support arch reaches a certain value, the bracket will compress, causing the surrounding rock to act on the U-shaped mine roof support. The pressure on the support arch is reduced, so as to prevent the support from being damaged due to the pressure of the surrounding rock being greater than the bearing capacity of the U-steel support arch.
According to the specific situation of the U-shaped steel arch support on site, flexibly select the model, structure and shed distance of the U-shaped mine roof support, and correctly guide the construction of the roadway U-shaped steel support to ensure its effective and reliable work, which is useful for accelerating the speed of roadway excavation and reducing later repairs of the roadway. It is of great significance to ensure safe production, extend the service life, obtain better technical and economic benefits, and give full play to the support performance of the mine roof support.
Similar supporting products include mining steel, U-shaped steel arch support, light rail and other mining steel products. Our company independently produces and processes various mining materials such as U-shaped steel supports, miner steel supports, cables, anchor rods, pallets, and single hydraulic props.
The application of U-shaped steel straight wall semicircular mine roof support in mining the intersection of roadway has achieved remarkable results. The use of U-shaped steel retractable support has better solved the problem of excavation and support.
