The steel arch support is a kind of passive support for coal mine support. It has high tensile strength and compressive strength, good toughness, high supporting force, large supporting strength and can be used repeatedly. Steel arch support is widely used. Mine roadways, especially in deep complex roadways and soft coal seam roadways.
U-shaped steel arch support are used for mining support equipment. The structure is simple and can be recycled. U-shaped steel arch support are subject to high pressure, long support time, simple installation and deformation, which is a good choice. The application of U-shaped steel straight wall semi-circular steel arch support shed in the intersection of mining and roadway has achieved remarkable results. U-shaped steel arch support is used to solve the problem of driving support. Compared with other rigid supports, U-shaped steel brackets have shrinkage, stable and reliable bearing capacity, adapt to the load and deformation of soft surrounding rock, high utilization rate of sections, convenient support of brackets, small maintenance, high recovery rate of brackets, and reduced pits. Wood use, environmental benefits are very obvious. The steel arch support is safe and reliable, effectively reducing the occurrence of accidents such as roofing and sheet metal, and improving the stability of the mine ventilation system. The use of U-shaped steel arch support improves the safe production conditions of mines, reduces production costs, meets the policy of replacing steel with steel, and has better environmental protection benefits and social and economic benefits.
