Steel mine support is a kind of passive support for coal mine support. Steel mine support has high tensile strength and compressive strength. At the same time, the steel mine support has good toughness, high supporting force and strong support strength. Steel mine support can be used multiple times and is widely used. Used in mine roadways, especially in deep complex roadways and soft coal seam roadways.
According to the specific situation of the site, flexibly select the model, structure and shed distance of thesteel Steel mine support, correctly guide the construction of the tunnel and mine support, ensure its effective and reliable work, and accelerate the speed of tunnel excavation, reduce the amount of repairs in the later stage of the tunnel, and ensure safe production steel mine support is of great significance to extend the service life, obtain better technical and economic benefits, and give full play to the support performance of the support. Similar supporting products include mining steel, U-shaped steel, light rail and other mining steel. And independently produce and process various mining materials such as U-shaped steel supports, miner steel supports, cables, anchor rods, pallets, and single hydraulic props. The application of mine supports and sheds in mining quasi roadway intersections has achieved remarkable results. The use of U-shaped steel retractable supports has better solved the problem of excavation and support.
The best stress state of the Steel mine support is that the back wall is filled and compacted to make it evenly compressed. When the pressure value of the surrounding rock used on the mine support reaches a certain value, the support will compress, causing the surrounding rock to act on the mine support. The pressure drops, so as to prevent the support from being damaged by the surrounding rock pressure being greater than the bearing capacity of the mine support.
