U Steel Arch is a passive support for coal mine support. It has high tensile strength and compressive strength. At the same time, it has good toughness performance, high support force, strong support strength, can be used multiple times, and it is widely used in mine u lane, especially in deep and complicated roadways and soft coal seam roadways.
The optimal stress state of the U steel arch is that the wall is filled and compacted to make it evenly compressed. When the pressure of the surrounding rock on the U-shaped steel support reaches a certain value, the support will compress and the pressure on the section steel support is reduced, so as to prevent the surrounding rock pressure from being greater than the bearing capacity of the u steel arch and causing the support to break.
According to the specific conditions of the site, flexibly choose the model, structural form and shed distance of the U steel arch, correctly guide the construction of the U-shaped steel support of the roadway, ensure its effective and reliable work, and speed up the tunneling speed and reduce the amount of later repairs of the roadway to ensure It is of great significance to safely produce, extend the service life, obtain better technical and economic benefits, and give full play to the support performance of the bracket.
