Equipment that breaks rock without breaking rules

Six product lines covering every stage of non-explosive rock excavation — from drilling and splitting to CO₂ gas fracturing and liquid oxygen systems.

DL-108 · DL-73 · DL-51

CO₂ Gas Fracturing System

Liquid CO₂ heated to 3000 bar expansion pressure fractures rock through gas pressure — not detonation. No explosion, no fly rock, no toxic fumes. Tubes reusable up to 1000 cycles. Ideal for coal mines, urban tunneling, and gas-rich environments where explosives are prohibited.

Pressure: 3000 bar
Tube Life: 1000×
Hole Dia: 130–140 mm
Depth: 6–8 m

Φ40 × 1.0 / 1.5 / 2.0 m

Disposable CO₂ Fracturing Tube

Single-use chemical fracturing tube for sites without liquid CO₂ supply. Ignites via exothermic compound — same gas-pressure principle, no CO₂ logistics required. Moisture-proof packaging for tropical and marine shipping.

How CO₂ gas fracturing works

A six-step process that delivers powerful rock breaking without explosives. The same principle applies across our fracturing tube and LOX product lines.

Drill Holes

130–140 mm diameter, 6–8 m depth, spaced by burden calculation.

Fill CO₂

Charge the reusable tube with liquid CO₂ using the filling station.

Insert Tube

Place the charged tube into the drilled hole with an excavator or crane.

Seal & Connect

Tamp the hole with stemming material. Connect ignition wires in series.

Ignite

Activate the detonator. CO₂ expands to 3000 bar in milliseconds.

Rock Breaks

High-pressure gas fractures the rock along natural bedding planes. Retrieve tube for reuse.
