[Industry News] Carbon Dioxide Fracturing Technology Accelerates Its Replacement of Traditional Blasting—Green Mine Construction Enters a “New Era of Safe Rock Breaking”

As the country’s requirements for mine safety and environmental protection continue to rise across the board, the limitations of traditional dynamite blasting in mining operations are becoming increasingly apparent: complex approval processes, controlled transportation, significant ground vibration, and severe dust pollution—all of which pose numerous risks to the surrounding environment and the safety of personnel. Meanwhile, a safer, more environmentally friendly, and easier-to-approve rock-breaking method—**carbon dioxide physical fracturing technology (CO₂ blasting)**—is rapidly gaining popularity in the mining industry.

As can be seen from the on-site images, a precise, non-detonative fracturing operation is underway at a large open-pit mine. The dust cloud generated by the blast rises smoothly and steadily, while the surrounding rock walls remain stable with no obvious signs of vibration or cracks. Engineering vehicles parked nearby are safely stationed. This real-world scenario vividly demonstrates a typical application of CO₂ fracturing in open-pit mining: Controllable, safe, environmentally friendly, low vibration 。

As a domestic enterprise specializing in the R&D and manufacturing of CO₂ fracturing equipment, Chongqing Chuangpuda Machinery Technology Co., Ltd. We are actively promoting the rapid adoption of this technology across the national mining engineering sector, providing the industry with safer rock-breaking solutions.

I. Why is CO2 fracturing now completely replacing traditional blasting?

Compared to traditional explosive blasting, CO₂ blasting uses... Physical Phase-Change Expansion Principle Liquid CO₂ is injected into a high-strength fracturing tube; upon activation, it instantly vaporizes and expands, generating immense pressure that fractures the rock formation. The entire process involves no flames, no deflagration, and no explosive characteristics.

The core advantages are as follows:

1. Ultra-high safety: No explosive properties, no sparks, and no deflagration.

No explosives transport permit required.

No need for pyrotechnic storage qualification.

There are no open flames or explosive hazards associated with conventional blasting.

Mine workers' safety risks reduced by more than 70%

2. Significant environmental advantages: No smoke, no explosive shockwave.

CO₂ is an inert gas that, once released, diffuses directly without leaving any residual pollution.
Applicable to:

Green Mine

Environmentally Sensitive Area

Construction near densely populated areas

3. Low vibration, greater controllability: Protects slopes and the overall structure.

Traditional blasting can easily trigger seismic waves and cause rock walls to loosen, whereas CO₂ fracturing releases energy more smoothly and is particularly well-suited for:

Slope stability zone

Geology sensitive to vibrations

Precisely control the rock-breaking range.

4. The approval process is faster, and the construction schedule is more controllable.

Since it is not classified as an explosive device, CO₂ fracturing does not require the cumbersome blasting approval process, significantly speeding up project progress and making it particularly suitable for:

Emergency construction

Nighttime construction

Multi-point synchronous excavation

II. Practical Applications in Mining Areas: A Safer, More Efficient Rock-Breaking Method

From the on-site images, it’s clearly visible that at the moment of blasting, the dust at the blast site rises smoothly and steadily, without the intense flames or shock waves typically associated with conventional explosive detonations—precisely the hallmark characteristic of CO₂ fracturing.

Application effects include:

1. High uniformity in rock mass fragmentation

It does not generate large flying rocks and does not compromise the safety of nearby construction personnel and equipment.

2. Suitable for large-scale continuous operations

Multiple points can be worked on simultaneously, enhancing the efficiency of mine stripping and mining operations.

3. Reduce equipment wear and tear in mining areas

Due to the reduced vibration, equipment such as excavators, trucks, and crushing stations suffer less damage, thereby lowering maintenance costs.

4. Improve the construction environment

Less dust and extremely low blasting noise, reducing the impact on surrounding communities.

III. Chuangpuda CO₂ Fracturing Equipment: The “Safety Revolutionary” in the Mining Industry

Chongqing Chuangpuda, leveraging a 38,000㎡ production facility and an ISO9001 quality management system, has launched a new generation... Carbon dioxide fracturing tube, fracturing controller, and injection system Possess:

● Higher pressure resistance (20% increase in pressure tolerance)

Adapts to complex rock formations and deep-hole operations.

● Leads to greater stability

Using new triggering technology, the error is reduced, and the construction pace has been improved.

● Lighter in structure and more convenient to carry.

Suitable for construction in narrow areas such as cliffs and caves.

● Modular design for easy maintenance

Significantly reduce the cost of complementary use.

It is currently being widely used in the following projects:

Open-pit mining and mountain stripping

High-efficiency rock breaking at the stone quarry

Water Conservancy and Slope Stabilization along Expressways

Urban basement expansion and excavation

Rock breaking in confined spaces such as power and communication tunnels.

IV. In the era of green mines, CO₂ fracturing will become the mainstream method for rock breaking.

As the country continues to promote “green, safe, and smart mines,” CO₂ fracturing stands out due to its:

✔ High security
✔ Low vibration
✔ Environmentally friendly and pollution-free
✔ Cost-controllable
✔ Simple approval

It is expected to become the mainstream technology for rock breaking in Chinese mines within the next five years.

Chongqing Chuangpuda will continue to focus on the R&D of CO₂ fracturing technology, providing more advanced and reliable rock-breaking solutions for mining operations, urban infrastructure projects, tunnel expansion, and other related engineering applications.
