Carbon Dioxide Fracturing System

I. Technical Features

  1. Pure Physical Rock Breaking: Utilizes liquid CO₂ phase transition (600× volume expansion, 200-300MPa pressure) for blasting without explosives, pollution, or vibrations.
  2. Precision Control: Energy direction and magnitude adjustable via shear discs (60-270MPa), adaptable to complex conditions.
  3. Eco-Friendly: Operating temperature range: -31.1℃~31.4℃; only emits CO₂ gas, no dust/harmful gases, preserving rock integrity.

II. Key Advantages

  • Safety: No explosive permits required; zero shockwaves/vibrations (0-60Hz), suitable for residential areas and gassy mines.
  • Efficiency: Single fracturing tube (e.g., 108# model) ≈2.22kg emulsion explosives, fracturing 75.6m³/hole (3m×3m spacing).
  • Economy: Tubes (42CrMo alloy steel) reusable 5000+ times, 40% lower cost vs traditional blasting.
  • Smart: Supports batch ignition (50 tubes/batch) with <0.1ms delay error; fill volume adjustable (0.5-8kg/tube).

III. Applications

  • Mining: Open-pit/underground blasting, coal seam permeability enhancement (3-5× gas extraction rate).
  • Civil Engineering: Foundation pits, subway tunnels (minimum 1m from structures).
  • Energy: Enhanced Geothermal Systems (EGS), creating 10-15× tube-diameter fracture zones.
  • Industrial: Clearing blockages in cement silos/blast furnaces, safe for high-temperature environments.

IV. Certifications
ISO 9001/MA certified, 23 national patents, deployed in 30+ countries globally.
