Rapid Phase Change
Liquid CO2 is heated within 20-40 ms by an electric activator. Instantaneous volume expansion of 600x generates 200-300 MPa of pressure inside the sealed steel tube.

Here is how CO2 fracturing performs where it counts.
PROCESS & EQUIPMENT / ON-SITE
No Explosives Required
100% physical rock breaking, no chemical reactions, open flames, or toxic gases. Eliminates blasting permits in regulated zones. Cannot be triggered by impact, friction, or static electricity.
14x Lower Vibration
0.18 cm/s at 30 m, vs 2.61 cm/s for conventional explosives. Below the strictest residential safety threshold of 1.0 cm/s. Ideal for urban sites, railways, and gas-rich mines.
600+ Cycles Per Tube
High-strength alloy steel tubes rated for hundreds of reuse cycles. Per-shot cost drops to a fraction of disposable alternatives after initial investment recovery.
3x Energy Utilization
300 MPa gas expansion pressure with optimized borehole layout. Outperforms conventional blasting in energy efficiency. More rock fractured per joule of input energy.

ON-SITE: CO2 MARBLE BLASTING
From filling to rock removal.
The CO2 fracturing cycle, phase by phase.
Pressure Relief & Jet Formation
At 60-270 MPa, adjustable, the rupture disc bursts. High-pressure CO2 exits as a high-velocity jet at hundreds of meters per second. Pure physical energy, no detonation.
Two-Stage Fracturing
Dynamic stress waves initiate primary cracks. Gas wedging drives high-pressure CO2 into the cracks until rock fragments completely. No flyrock beyond 5 m.
Two systems. One matched to your scale.
From precision underground work to heavy open-pit production.

CO2 fracturing vs. conventional explosives.
The headline numbers. Full data tables, including hydraulic splitters, live in the complete guide.
| Metric | CO2 Fracturing | Conventional Explosives |
|---|---|---|
| Vibration (30 m) | 0.18 cm/s | 2.61 cm/s |
| Flyrock Distance | Under 5 m | 50+ m |
| Blasting Permit | Not required | Required, often denied |
| Toxic Gas Emission | None, CO2 only | CO, NOx, SOx |
| Underground Use | Safe, spark-free | Prohibited in gas-rich mines |
Two paths. One for your volume.
Choose based on your regulatory environment and production volume.
Reusable Tubes
- High-strength alloy steel rated for 600+ cycles
- Higher upfront cost, dramatically lower per-shot cost
- Requires a tube recovery and refilling station
Best for: High-volume operations, permitted mining sites
Disposable Tubes
- Single-use sealed cartridge, no recovery system needed
- Lower upfront cost, higher per-shot cost
- Zero blasting permits required in most jurisdictions
Best for: Short-term projects, restricted zones, urban sites

Case Study / Colombia
Blasting permit denied 3 times. Then they switched.
A mining crew in Colombia's Antioquia region faced shutdown when regulators denied their blasting permit three times. Their quarry sat just 40 meters from homes.
After switching to a CO2 fracturing system, they achieved 1,500-2,000 m³ per shift with zero complaints and zero permit delays. The project is now in its fourth year of continuous operation.

Frequently asked questions.
The questions buyers ask most. Detailed answers live in the complete guide.
How much does a CO2 fracturing system cost?
A basic reusable system, including tubes, charging unit, and initiator, starts in the mid-five-figure USD range. Disposable tube systems have lower upfront but higher per-shot costs.
Contact us for a project-specific quote.
Do I need a blasting permit for CO2 fracturing?
In most jurisdictions, no. CO2 fracturing is classified as non-explosive physical rock breaking. Always check local regulations.
Our team provides technical documentation for permit applications.
What is the production rate per day?
In open-pit mines with a reasonable hole layout, a single 108# fracturing tube produces about 70 m³ of rock per hole. Reference pattern: 7 m deep holes on 3 m x 1.5 m spacing yield roughly 75.6 m³ per hole, about 3,780 m³ for 50 holes. Multi-tube setups scale production proportionally.
How does CO2 fracturing compare to hydraulic splitters?
CO2 fracturing handles larger volumes with less secondary breaking, especially in harder rock (UCS above 80 MPa). Hydraulic splitters are better for precision splitting in controlled environments.
Our comparison guide has the full data breakdown.
