U steel arch is a kind of passive support for coal mine. It has high tensile strength and compressive strength, good toughness, high support force, large support strength and can be used repeatedly. It is widely used in the mine U lane, especially in deep complex roadways and soft coal seam roadways.
Steel arch supports are used for roof support or ground control where severe conditions are anticipated or to maintain critical areas of a mine or tunnel where roof bolting or cribbing is not sufficient or practical. Used in conjunction with Camber Lagging systems, arches can solve difficult conditions on a long-term basis.
