The best stress is U-shape steel support after filling dense uniform compression, as used in the surrounding rock on the u-shape set pressure value reaches a certain value, the bracket can produce compression, the effect of surrounding rock in the pressure drop on the U-shape steel support, thereby avoid surrounding rock pressure is greater than the bearing capacity of u-shape steel support and make the stents.
According to the specific site conditions, the flexibility to choose model, structure form and the tent of U-shape steel support distance, roadway construction of u-shape set correct guidance, to ensure the effective and reliable to work, to speed up the drivage, reduce the amounts of the late repair, guarantee the safety in production, extend the length of service, achieve better technical and economic benefits, give full play to the bracket support performance has important significance. Similar support products also miners steel, U steel, light rail and other mining steel. And the independent production and processing of a variety of u-shaped steel support, miners steel support, cable, anchor, pallet, monomer hydraulic prop and other mining materials. Zhongxiang has also established long-term friendly cooperative relations with shougang, xuangang, hangang, wisco, angang and other major steel mills. Products long-term service in the national large, medium and small mining bureau, and exported to southeast Asia, west Asia and other regions. The application of the semicircle arch support ofU-shape steel support to the bifurcation point of mining roadway has achieved remarkable results.
