The steel mine support is a passive support for coal mine support. Steel mine support has high tensile strength and compressive strength. Steel mine support also has good toughness performance, high support force, high support strength, and can be used multiple times. Steel mine support is widely used in mine roadways, especially in deep complex roadways and soft coal roadways.
Steel mine supports are mainly used for secondary support of mine tunnels and mine tunnels through mountain tunnels. The optimal stress state of the steel mine support is that the main material of the steel mine support-U-shaped steel is evenly compressed after the wall is filled and compacted. When the surrounding rock pressure value used on the steel mine support reaches a certain value, the support will produce The compression reduces the pressure of the surrounding rock on the steel mine support, so as to avoid the pressure of the surrounding rock being greater than the bearing capacity of the steel mine support and damaging the support.
According to the specific conditions on site, flexibly choose the type, structure and shed spacing of the steel mine support, correctly guide the construction of the steel mine support of the tunnel, ensure its effective and reliable work, and speed up the tunneling speed, reduce the amount of roadway later repairs, and ensure It is of great significance to produce safely, extend service life, obtain better technical and economic benefits, and give full play to the support performance of steel mine supports.
