Special shape and force state
Shape basis: the special shape of Mine Roof Support is the basis for its support function.Mine Roof Support is usually made of hot rolled steel plate formed by cold bending, with U-shaped groove and legs on both sides. This shape makes the Support Arch better able to disperse and transfer the load when it is subjected to gravity or external force, and increases its load-bearing capacity.
Force state: The best force state of Support Arch is to make it uniformly pressurised after the wall is filled and compacted. When the pressure value of surrounding rock applied to Support Arch reaches a certain value, the bracket will produce compression, so that the pressure of surrounding rock acting on Support Arch decreases, thus avoiding the pressure of surrounding rock is greater than the bearing capacity of Support Arch and make the bracket damage.
Material characteristics and bearing capacity
Material selection: Mine Roof Support is usually made of high-quality steel, with high strength and rigidity. This makes the Mine Roof Support has a better bearing capacity and deformation resistance, can be in the gravity and the role of external forces to maintain the stability of the structure.
Connection method
Lap and connection: Mine Roof Support is usually connected with other components through bolts, welding or bayonet and other ways. These connection methods can make Mine Roof Support and other components closely combined to form a stable overall structure.
