Mine resin bolt support is inseparable from resin anchoring agents, bolts, steel belts, bolt trays, nuts and other materials, all of which have certain requirements. mine resin bolt

Material requirements for bolt support: steel strip or reinforced beam: the ultimate tensile strength of the material should not be less than 360Mpa. mine resin bolt

Mining bolt manufacturers should provide qualified and stable products. The color of the curing agent in the anchor must comply with industry standards. The properties, characteristics, dimensions, stirring time, initial setting time and correct use method of the anchoring agent should be described in the product manual. It is not allowed to mix anchoring agents and resin anchoring agents from different manufacturers in the mine.

The warehouse manager responsible for the bolt brackets must register the product name, specification, quantity, production date, arrival time and distribution of each batch of products. The storage period does not exceed the requirements of the product specification, and the warehouse temperature is 4-25 °C. Anchor rods (including truss tie rods, etc.): the tensile yield strength of the metal rod body is not less than 320MPa, the ultimate tensile strength is not less than 500MPa, and the elongation is not less than 16%. mine resin bolt
