U-shaped steel support is mainly composed of 1 top beam, 2 supporting legs, 4 clamping cables and 2 bottom plates. It is mainly used for secondary support of mine roadway, mine roadway and support of tunnel through mountain. U-shaped steel support is characterized by high pressure, long supporting time, easy installation and non-deformation.
The application of the semicircle arch support of u-shaped straight wall to the bifurcating point of mining roadway has achieved remarkable results. Compared with its stable and reliable bearing capacity, u-shaped steel support can adapt to the load and deformation of soft surrounding rock, with high utilization rate of section, convenient support, small amount of maintenance, high recycling reuse rate of support, reducing the use of pit wood, and obvious environmental benefits.
The use of u-shaped steel support is reliable, which can effectively reduce the occurrence of roof caving and sheet side accidents, and improve the stability of mine ventilation system.
