O2 Rock Blasting System for Underwater Rock Breaking | Safe & Low‑Shock Underwater Blasting Technology

H1: O2 Rock Blasting System for Underwater Rock Breaking

The O2 Rock Blasting System is a second‑generation gas rock blasting technology designed for safe, efficient and eco‑friendly rock breaking — especially in underwater and water‑rich environments.
Instead of traditional explosives and detonators, the system uses liquid oxygen as the energy source to break rock while keeping water shockwave and vibration at a much lower level.

This makes O2 rock blasting an ideal solution for underwater construction, reef removal, port deepening and other projects where conventional explosives are restricted or cause too much risk to nearby structures and the marine environment.

H2: How O2 Rock Blasting Works

The O2 Rock Blasting System uses liquid oxygen (LOX) and a specially designed blasting device. After charging, the liquid oxygen gradually turns into gas and mixes with fuel in a confined space. When ignited, the rapid phase transition and combustion create high‑pressure gas, which expands and breaks the surrounding rock mass.

Key working principles:

• Liquid oxygen is filled into the blasting device inside the drilled hole

• LOX changes to gaseous oxygen and mixes with fuel in a confined space

• Ignition triggers rapid gas expansion and high pressure

• Rock is fractured by gas pressure and tensile stress rather than a high‑detonation shockwave

• If not ignited within about 10–20 minutes after charging, the system becomes inactive and no longer has blasting conditions

Because the main effect is high‑pressure gas rather than a strong detonation shockwave, water shockwave and far‑field vibration are significantly reduced compared with traditional explosives.

H2: Why Choose O2 Rock Blasting for Underwater Projects?

H3: Safe by Nature – No Traditional Explosives or Detonators

• No conventional explosives, detonators or restricted blasting materials

• The charging becomes naturally inactive if it is not ignited within 10–20 minutes

• Greatly reduces storage, transportation and on‑site safety risks

• Easier to manage in areas with strict explosive control and permitting

H3: Low Water Shockwave and Vibration

Independent underwater tests by professional institutes show:

• Peak overpressure of water shockwave is significantly lower than that of emulsion explosives under similar conditions

• Vibration attenuates faster in the far field, reducing the impact on nearby structures and equipment

• Suitable for underwater blasting near bridges, ports, dams, pipelines and other sensitive facilities

This low‑shock performance is a key advantage in underwater rock blasting, where protecting structures and marine life is critical.

H3: High Rock Breaking Efficiency

• Second‑generation gas rock blasting technology with higher energy utilization

• Compared with first‑generation CO₂ rock blasting, O2 rock blasting can achieve higher efficiency and lower operating cost

• Effective for hard rock, jointed rock mass and complex geology in underwater conditions

• Can be used as a strong supplement to traditional explosives where partial rock removal or precision blasting is needed

H3: Eco‑Friendly and Green Blasting Solution

• Main reaction by‑products are carbon dioxide (CO₂) and water

• No toxic fumes and no solid explosive residue

• Lower impact on water quality and marine environment compared with many traditional explosives

• Especially suitable for environmentally protected waters, fisheries and tourism areas

H2: Typical Applications of O2 Underwater Rock Blasting

The O2 Rock Blasting System can be applied to many underwater and water‑rich projects, including:

• Underwater rock and reef removal for navigation channels

• Port and fairway deepening near wharfs and terminals

• Underwater foundation and pile construction for bridges and piers

• Rock excavation around dams, cofferdams and hydropower projects

• Tunnel portals and shafts in water‑rich geology

• Urban and sensitive projects where the use of conventional explosives is restricted

• Emergency rock breaking where safety, vibration and environmental impact must be strictly controlled

H2: Advantages Compared with Traditional Underwater Explosives

Note: O2 rock blasting is not intended to completely replace explosives in all conditions. It works as a powerful complementary method and is particularly valuable where safety, vibration and environmental protection are critical.
