CO2 Gas Fracturing System
Safe, Efficient, and Environmentally Friendly Rock Breaking Solution for Mining, Quarrying, and Tunnel Excavation
Key Advantages
No Explosives
100% physical rock breaking – no chemical reactions, open flames, or hazardous gases
Minimal Vibration
Low-frequency operation (0-100 Hz) ideal for urban areas and residential zones
Reusable Tubes
Steel pipes can be used hundreds of times, significantly reducing operational costs
High Efficiency
3x higher energy utilization than conventional blasting – optimized hole pattern design
Product Specifications
51# System: Ideal for underground mining and precision work | 108# System: Ideal for open-pit mining and large-scale quarrying
How It Works
Rapid Phase Change
Liquid CO₂ is heated rapidly within 20-40 milliseconds by an electric activator. The liquid undergoes phase transition to gaseous or supercritical state, causing instantaneous volume expansion of over 600 times and generating extreme pressure (200-300 MPa).
Pressure Relief & Jet Formation
When pressure exceeds the rupture threshold (60-270 MPa adjustable), the pressure-relief disc bursts, releasing high-pressure CO₂ gas as a high-speed jet through the nozzle, reaching hundreds of meters per second.
Two-Stage Fracturing
Dynamic Stress Wave: The jet creates shock waves, initiating primary cracks. Gas Wedging: High-pressure gas infiltrates cracks, driving propagation until rock fragments completely.
