What Is an Explosion-Proof Water Trough?
1. What Is an Explosion-Proof Water Trough?
An explosion-proof water trough is a passive explosion prevention device widely used in coal mines, tunnels, and mines where gas or coal dust explosions are likely to occur.
It is usually a trapezoidal, brittle, hard plastic container (commonly made of ABS or PVC) filled with water.
When an explosion shock wave occurs, the container instantly shatters, releasing a large amount of water mist to block the propagation of flames and high-temperature gases, effectively breaking the explosion chain and preventing the disaster from spreading.
2. What Is an Explosion-Proof Water Bag? (Core Keyword Explanation)
Many people ask: “What is an explosion-proof water bag?”
An explosion-proof water bag works on the same principle as a water trough — it releases water mist triggered by an explosion shock wave to stop the explosion from spreading. The main differences are:
- Water Bag: Made from flexible material (e.g., high-strength explosion-proof film), suitable for confined spaces, narrow turns, or areas requiring flexible arrangement.
- Water Trough: Made from rigid material, with larger capacity and wider explosion prevention coverage, suitable for large cross-section roadways and main transport tunnels.
In a coal mine safety system, both water bags and water troughs are often used together to create multiple explosion protection layers.

3. Core Functions of Explosion-Proof Water Troughs
- High-Efficiency Explosion Isolation
When triggered, the water mist forms a barrier at least 5m long, 3.5m wide, and 3m high, effectively blocking flame spread. - Fire Suppression & Cooling
The released water mist rapidly absorbs heat, lowering the temperature and reducing the risk of secondary explosions. - Shock Wave Mitigation
Water mist significantly cushions the explosion shock wave, reducing damage to equipment and injury to personnel.
4. Structure & Performance Features
- Flame-Retardant Engineering Plastic Alloy (e.g., ABS): Heat-resistant, anti-static, smooth surface, well-sealed, breaking pressure ≤ 16kPa.
- Corrosion-Resistant Materials: Options include galvanized steel plate or high-strength engineering plastic for humid, high-temperature environments.
- Large Water Capacity: Ensures sufficient mist generation to cut off the explosion chain.
- Flexible Installation: Can be hung from tunnel ceilings or mounted on brackets; easy to install and maintain.
- Durable & Long Service Life: Impact-resistant, anti-aging, suitable for long-term underground use.
5. Common Product Models
| Model | Volume (L) | Size (mm) | Weight (kg) | Application Environment | Installation Method |
|---|---|---|---|---|---|
| GS40 | 40 | Custom/Standard | ≈15-20 | Gas/coal dust explosion zones | Hook suspension/bracket mount |
| GS60 | 60 | Custom/Standard | ≈20-25 | Gas/coal dust explosion zones | Hook suspension/bracket mount |
| GS80 | 80 | Custom/Standard | ≈25-30 | Gas/coal dust explosion zones | Hook suspension/bracket mount |
6. Installation & Maintenance Requirements
- Placement: Main transport tunnels, centralized mining area tunnels, return airways, high coal dust risk zones.
- Water Volume Standard: Each trough should be filled with 30L of water; total water volume should be ≥ 200L per square meter of tunnel cross-section.
- Maintenance: Hanging height 20cm from roof, row spacing 1.2–3m, gap spacing 0.02–0.04m; regularly check sealing and water levels.
7. Application Scenarios
- Underground mining faces
- Main transport tunnels
- Return airways
- High-risk areas for gas and coal dust explosions
- Other mines or industrial underground facilities
8. Selection & Safety Recommendations (SEO Content Extension)
When choosing between an explosion-proof water trough and a water bag, consider:
- Tunnel Cross-Section Size: Large cross-sections and main tunnels are better suited for rigid, large-capacity water troughs.
- Space Conditions: Narrow tunnels or curved roadways suit flexible water bags.
- Explosion Coverage Needs: Design protective zones according to mine safety plans, covering all critical positions.
- Compliance with Standards: Refer to MT 694-1997 “Technical Conditions for Mine Explosion-Proof Water Trough Devices” and relevant international explosion-proof standards.
9. Conclusion
Whether using explosion-proof water troughs or water bags, their mission is the same — to protect lives, reduce equipment loss, and prevent disaster escalation when an explosion occurs.
Scientific selection and proper layout are essential for safe production in coal mines, tunnels, and other underground projects.
