Carbon Steel Mining Accessories Dome Bolts
These dome bolts are specialized mining accessories made of carbon steel, designed primarily for underground mining support. Carbon steel provides high strength and wear resistance, enabling the bolts to withstand the pressure and harsh conditions of mining environments. Their dome-shaped head design ensures stable contact with mine rock surfaces or support structures, enhancing overall support reliability. As essential mining accessories, they are widely used to reinforce roadways, tunnels, or working faces, helping maintain the safety and stability of mining sites.
Product Specifications
Parameter Category Specification Details
Product Type Dome bolts (specialized carbon steel accessories for underground mining support)
Material Carbon steel (Q235/Q345/Q460) - offers high tensile strength and wear resistance for mining harsh conditions
Application Reinforcing mining roadways, tunnels, underground working faces; supporting mine rock walls/roofs
Standard Sizes - Diameter: 16mm-24mm (common mining bolt sizes)
- Length: 1000mm-2400mm (adjustable per support depth needs)
Dome Head Dimensions Diameter: 30mm-50mm; Thickness: 8mm-15mm - ensures large contact area with rock/support structures
Tensile Strength 345MPa-460MPa (varies by carbon steel grade; meets mining load-bearing requirements)
Surface Treatment Hot-dip galvanizing / Zinc plating - anti-rust and corrosion resistance for humid underground environments
Thread Type Metric coarse thread (ISO standard) - easy to install with matching nuts/washers
Applications
  • Reinforcing underground mining roadways to prevent rock collapse using carbon steel dome bolts
  • Supporting the roofs of mining tunnels with high-strength carbon steel dome bolts
  • Securing rock walls in underground mining working faces to maintain stability
  • Strengthening temporary mining passages during ore extraction operations
  • Reinforcing the surrounding rock of mining shafts to ensure structural safety
Frequently Asked Questions
Q: Why are these dome bolts made of carbon steel, and what advantage does this material bring for mining use?
A: Carbon steel (e.g., Q235/Q345) provides high tensile strength and wear resistance. These properties let the bolts withstand underground mining's harsh conditions—like rock pressure and humidity—without easily deforming or breaking.
Q: What makes the "dome head" design suitable for mining support?
A: The dome-shaped head has a larger contact area with rock surfaces or support structures. This design distributes pressure more evenly, preventing the bolt from sinking into soft rock and improving overall support stability.
Q: Are these dome bolts only used for specific parts of a mining site?
A: No, they're versatile mining accessories. They're commonly used to reinforce underground roadways, tunnel roofs, working faces, and even mining shafts—any area that needs rock wall or roof support.
Q: What sizes do these carbon steel dome bolts come in, and how to choose the right one?
A: Standard diameters range from 16mm-24mm, and lengths from 1000mm-2400mm. Choose based on the support depth needed (e.g., longer bolts for deeper rock layers) and the expected pressure at the mining site.
Q: Do these bolts have any protection against underground humidity?
A: Yes, they use surface treatments like hot-dip galvanizing or zinc plating. These treatments provide anti-rust and corrosion resistance, extending the bolts' service life in humid underground environments.
