Noise Challenges in Coal Mine Ventilation Shafts
In the coal mining industry, ventilation shaft systems are critical for ensuring safe air circulation. However, fans generate aerodynamic noise, mechanical vibration noise, and resonance noise, which not only impact workers’ health but can also pose safety risks. To address this issue, SINOYQX melamine foam, with its outstanding sound absorption performance and flame-retardant properties, has become the ideal material for coal mine ventilation noise control.

Coal Mine Ventilation Noise Challenges
Coal mine ventilation fans often operate at noise levels exceeding 90dB, sometimes reaching 96dB, which surpasses the long-term safe exposure limit for humans. Without effective noise control, this can lead to hearing damage, communication difficulties, and safety risks for miners. Additionally, fan-generated noise may spread to surrounding mining areas, affecting the local environment and nearby residents.
SINOYQX Melamine Foam – The Ultimate Choice for Noise Reduction
SINOYQX melamine foam is an ultra-lightweight, high sound-absorbing, and flame-retardant open-cell foam material designed for high-noise environments. Its unique three-dimensional open-cell structure provides excellent sound absorption capabilities, making it particularly suitable for controlling noise from ventilation fans in coal mines.
Key Advantages of SINOYQX Melamine Foam:
✅ High-Efficiency Sound Absorption & Wide-Frequency Noise Reduction
With a 99% open-cell rate, the foam effectively absorbs noise across low, mid, and high frequencies, making it ideal for reducing aerodynamic noise from ventilation fans.

✅ Ultra-Lightweight & Easy to Install
With a density of only 4-12 kg/m³, it significantly reduces structural load compared to traditional metal or concrete acoustic materials, making installation and maintenance more convenient.
✅ B1 Flame Retardant & Safe for Hazardous Environments
Compliant with GB 8624 B1 and DIN 4102 B1 flame-retardant standards, it does not contribute to combustion or release toxic gases, ensuring safety in high-risk environments such as coal mines.
✅ High Temperature & Chemical Resistance
Withstands extreme temperatures from -180°C to 240°C and is resistant to moisture, coal dust, and acidic/alkaline gases, ensuring long-term durability in coal mine conditions.
✅ Eco-Friendly & Non-Toxic
Free from fiberglass, formaldehyde, and other harmful substances, it does not affect mine ventilation quality, creating a healthier working environment for miners.
Versatile Applications for Comprehensive Noise Reduction
🔹 Duct Sound Absorption Linings: Applying SINOYQX melamine foam panels inside ventilation ducts and fan outlets helps reduce noise reflection and enhances silencing effects.
🔹 Silencing Chambers & Mufflers: Installing silencing chambers filled with melamine foam at fan inlets and outlets minimizes aerodynamic noise.
🔹 Equipment Noise Insulation: Wrapping ventilation fans, ducts, and transformers with melamine foam provides effective noise insulation, preventing sound propagation.
Proven Results in Coal Mine Noise Reduction
In a large-scale coal mine ventilation shaft renovation project, the implementation of SINOYQX melamine foam for noise control successfully reduced noise levels from 96dB to 75dB, meeting national environmental and safety standards. This significantly improved the working conditions for miners. Compared to traditional noise control materials, SINOYQX melamine foam achieved 15%-30% better noise reduction performance while lowering maintenance costs.
Conclusion: SINOYQX Melamine Foam – The Best Choice for Coal Mine Noise Control
