(Revolutionary Physical Rock-breaking Solution)
Core Principle
Based on liquid CO₂ supercritical phase-change physical expansion technology, the system utilizes electric heating to vaporize liquid CO₂ within 20–40 milliseconds, achieving 600× volume expansion and releasing 200–300 MPa high-pressure gas energy. This creates a multi-directional fracture network in rock masses through pure physical reactions—no chemical processes, open flames, or harmful gases. Energy release direction and magnitude are precisely controlled via adjustable shear discs (60–270 MPa).
Technical Advantages
| Dimension | Key Benefits |
|---|---|
| Safety | Eliminates explosive permits; zero shockwaves/vibrations (0–60 Hz); suitable for residential areas and high-gas mines. |
| Eco-friendly | Only emits CO₂; no dust/toxic gases; low-temperature expansion (-31.1°C to 31.4°C) preserves rock integrity. |
| Efficiency | Single fracturing tube (e.g., 108# model) delivers energy equivalent to 2.22 kg emulsion explosives, fracturing 75.6 m³/hole (3m×3m grid). |
| Cost-saving | Reusable tubes (42CrMo alloy steel, 5000+ cycles) reduce total costs by 40% vs. traditional blasting. |
| Precision | Customizable via CO₂ filling (0.5–8 kg/tube), shear disc thickness, and heater types for pressure optimization. |
