In the realm of quarrying and mining, the efficiency and safety of rock blasting methods are paramount. Traditional explosives have been the cornerstone of rock fragmentation for decades, enabling the extraction of valuable stone materials. However, as industries evolve, so do the technologies that support them. Enter the CO2 Rock Blasting System Technology and its advanced successor, the O2 Rock Blasting System Technology. This article delves into a comparative analysis of these two innovative systems, highlighting their roles, advantages, and the evolutionary journey from CO2 to O2 technologies in addressing the limitations of traditional explosives.

Before using the O2 rock blasting system, many customers are unsure whether this new technology is suitable for their application scenarios. As a professional factory, we have collected many questions that customers are very concerned about, and we have summarized some answers for potential partners to refer to.

Carbon dioxide blasting offers a safer, non‑explosive alternative to conventional rock blasting. The system pressurizes a tube with liquid CO2 (5–9 MPa); an electric heating charge instantaneously vaporizes it, expanding ~600× to generate a >300 MPa shock that fractures rock along natural cracks. Carbon dioxide blasting is low‑emission, reduces vibration and toxic gases, uses reusable tubes and replaceable heat charges, and enables controlled, efficient pre‑cracking for mining and tunneling.
