Galvanized anchor rod for mining is a kind of support equipment widely used in mining engineering. It combines galvanizing anti-corrosion technology and the support function of anchor rod, and has unique advantages and application value. The following is a detailed introduction to galvanized anchor rod for mining:
1. Definition and characteristics
Definition: Galvanized anchor rod for mining is an anchor rod with galvanized surface, usually made of high-quality steel, with high strength, corrosion resistance, easy installation and other characteristics.
Features:
1. Excellent mechanical properties: Galvanized anchor rod is made of high-quality steel, and has high strength and toughness after special treatment, and can withstand large tension and pressure.
2. Corrosion resistance: The galvanized layer has good corrosion resistance, can resist erosion by environmental factors such as atmosphere, water and soil, and prolong the service life of the anchor rod.
3. Easy installation: Galvanized anchor rods are generally connected by threads, which are easy and quick to install and can improve construction efficiency.
2. Application fields
Galvanized anchor rods for mining are widely used in mining projects, mainly including the following aspects:
1. Tunnel support: In the tunnel excavation and support process of coal mines and non-coal mines, galvanized anchor rods are used as the main support material to effectively enhance the stability and safety of the tunnel.
2. Goaf management: In goaf management, galvanized anchor rods can be used in conjunction with other support materials to form a stable support structure to prevent goaf collapse and geological disasters.
3. Slope reinforcement: In the mine slope reinforcement project, galvanized anchor rods can be driven into the slope rock and soil, and closely combined with the rock and soil through grouting and other methods to improve the stability and anti-slip ability of the slope.
3. Technical parameters
The technical parameters of galvanized anchor rods for mining vary depending on the specifications and uses, but generally include the following:
Diameter: Common diameters are 16mm, 18mm, 20mm, 22mm, etc.
Length: Designed according to specific engineering needs, generally ranging from a few meters to more than ten meters.
Yield strength: generally not less than 345MPa, to ensure that the anchor has a certain resistance when subjected to external force.
Tensile strength: generally not less than 510MPa, to ensure that the anchor will not break when subjected to tension.
Elongation: generally not less than 25%, to ensure that the anchor has a certain deformation capacity when subjected to external force.
IV. Purchase suggestions
When purchasing galvanized anchor rods for mining, the following factors should be considered:
1. Manufacturer qualifications: select manufacturers with production qualifications and good reputation to ensure the quality and after-sales service of the anchor rods.
2. Product quality: check the material, galvanized layer thickness, surface quality, etc. of the anchor rod to ensure compliance with relevant standards and engineering requirements.
3. Technical parameters: select appropriate technical parameters such as diameter, length, strength, etc. according to specific engineering requirements.
4. Price factors: reasonably control procurement costs while ensuring that quality and technical parameters meet requirements
