Main uses and advantages of U-shaped Steel Arch Support——U-shaped steel support is a kind of passive support srch for coal mine support. It has high tensile strength and compressive strength, and has good toughness performance, high support force and high support strength. It can be used many times and is widely used. In mine roadway, especially in deep complex roadway and soft coal seam roadway.
U-shaped support archs are mainly used for secondary support of mine tunnels and mine tunnels through mountain tunnels.
The obvious advantages of U-shaped Mine Roof Support:
Compared with other rigid supports, U-shaped mine roof supports have shrinkability, stable and reliable bearing capacity, adapt to the load and deformation of soft surrounding rock, high section utilization rate, convenient support support, small maintenance, high support recovery and reuse rate, and reduce pits. The use of wood has obvious environmental benefits.
