Steel mine support refers to the artificial structure installed in the mine roadway to support the rock. Its function is to control the movement of surrounding rock and prevent the surrounding rock fr

The mine roof support has the advantages of high initial support force, large support strength, easy installation and not easy deformation, etc., so it is often used for the manufacture of tunnel flex

Support arch main features: high pressure, long support time, easy installation and deformation.

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

I-beam, also known as steel beam, is a long piece of steel with an i-shaped section. I - beam is divided into ordinary i-beam and light i-beam, H - beam three kinds. I-beam is widely used in various c

The initial investment of u-shaped steel support is high. In the long run, it has a good effect of forming a roadway at one time, small deformation, small maintenance amount, less material input and h
