Application Scenario

In coal mines, liquid CO₂ is used for coal seam fracturing to enhance permeability and gas drainage, and liquid nitrogen is used for underground fire prevention and extinguishing and shaft freezing construction; surface coal preparation plants use liquid oxygen with ozone for wastewater treatment, providing low-temperature gas support throughout the whole coal mining process.

Supporting Equipment

• 5-30m³ low-temperature liquid CO₂ storage tanks
• Low-temperature liquid nitrogen storage tanks
• High-pressure cryogenic filling pumps
• Vaporizers and pressure reducing systems
• Underground special low-temperature delivery pipelines

Solution Advantages

Liquid CO₂ fracturing is safer than explosives with no blasting shock wave, suitable for high-gas mines; liquid nitrogen fire extinguishing can quickly suffocate underground fires without re-ignition risk; we provide MA-certified equipment specially for coal mines, complying with underground safety regulations.
