Instruction

Is a kind of passive support, u-shape set higher tensile strength, compressive strength, good toughness properties at the same time, high support, support strength, can be used multiple times, is widely used in mine roadway, especially in deep roadway and complex soft coal seam roadway.

Application

 u-shape set for semi-finished products of mine roadway supporting and secondary u-shape set mine laneway in mountain tunnel.

Advantages

 Than other rigid support u-shape set with yielding and carrying capacity of the stable and reliable, to adapt to the load and deformation of the soft surrounding rock, the section utilization ratio is high, support the back is convenient, small amount of maintenance and support recycling reuse rate is high, reduce timber use and environmental benefit is obvious.

Strained condition
