Support arch is a kind of passive support for coal mine support. It has high tensile strength and compressive strength, and also has good toughness performance. Support arch has high supporting force and strong supporting strength. It can be used multiple times and is widely used. Mine u lanes, especially in deep complex roadways and soft coal seam roadways. The support arch steel has stable performance, reasonable structure, good strength and rigidity.
Support arch are used for secondary support of mine tunnels and mine tunnels of mountain tunnels. Arch supports are classified by purpose: steel supports for coal mines, steel supports for iron mines, steel supports for gold mines, steel supports for copper mines, steel supports for lead-zinc mines, steel supports for railway and highway tunnels, steel supports for diversion culverts of hydropower stations .
The support arch has the characteristics of light weight, small weight per section, complex deformation, multiple rolling passes, rapid temperature drop of the rolled piece, and the rolling piece is not easy to go out of groove. China Coal Group can tailor-made arch brackets, miner steel brackets, and I-steel brackets as well as supporting card holders and connecting plates according to the actual needs of customers. Welcome new and old customers to consult and visit.
