Detailed Specifications & Features
Dome Ball Washer Mining Accessories
This dome ball washer is a specialized accessory for underground mining operations, designed to work with mining bolts and nuts in support systems. Its integrated "dome" and "ball" structure allows slight angular adjustment during installation, ensuring tight fit with uneven rock surfaces or mining support structures. Made of high-strength materials and often treated with anti-rust finishes, it withstands the pressure, humidity, and wear of mining environments. As a key part of mining support, it enhances the stability of bolted connections, helping maintain the safety of roadways, tunnels, and working faces.
Technical Specifications
| Parameter Category | Specification Details |
|---|---|
| Base Material | Carbon steel (Q235/Q345) - standard for general mining; High-strength alloy steel - optional for high-pressure mining areas |
| Load-Bearing Capacity | 15kN-60kN (varies by material and size; matches paired mining bolts) |
| Surface Treatment | Hot-dip galvanizing (standard anti-rust for humid mines); Zinc plating - optional for less harsh underground environments |
| Compatibility | Fits common mining bolt diameters (16mm-24mm); compatible with most mining nut types |
| Industry Compliance | Complies with mining equipment standards (e.g., GB/T 15389-2017; aligns with international mining support specs) |
Applications
- Matching mining bolts to reinforce underground roadways, using the dome ball washer to adapt to uneven rock surfaces
- Enhancing bolt-nut connection stability in mining tunnels with high-strength dome ball washers
- Supporting rock walls in underground mining working faces by pairing dome ball washers with mining bolts
- Using anti-rust dome ball washers in humid mining environments to maintain long-term support reliability
- Adjusting for slight angle differences when securing temporary mining passages with mining bolt systems
Frequently Asked Questions
What makes the "dome ball" structure special for mining use?
The combined dome and ball design allows 5°-15° of angular adjustment. This lets the washer fit uneven rock surfaces common in mines, ensuring the bolt-nut system stays tightly connected instead of loosening due to surface irregularities.
What role does this dome ball washer play in mining support systems?
It acts as a key matching accessory for mining bolts and nuts. It distributes the pressure from bolts evenly onto rock surfaces, enhances the stability of the entire connection, and prevents the bolt from breaking or slipping under mining pressure.
Can this washer be used with any mining bolt, or does it need specific matching?
It's compatible with most common mining bolts, specifically those with diameters ranging from 16mm-24mm. It also works with most standard mining nut types, so you just need to match the washer size to the bolt diameter.
Why is the washer made of carbon steel, and can it handle harsh mining conditions?
Carbon steel (Q235/Q345) provides high strength and wear resistance, which is essential for withstanding underground mining pressure. Plus, with anti-rust treatments like hot-dip galvanizing, it can resist humidity and corrosion in mines.
Is there a difference in how this washer is used for tunnels vs. roadways in mines?
The core function is the same—adapting to uneven surfaces and stabilizing connections. For high-pressure tunnels, you might choose a washer made of high-strength alloy steel; for standard roadways, the carbon steel version works well.
