In the demanding fields of quarrying and tunneling, efficient and safe rock fragmentation methods are essential for maintaining productivity and ensuring the safety of workers. Traditional explosives have long been the backbone of rock blasting operations, enabling the extraction of valuable stone materials. However, as industries evolve, so do the technologies that support them. One such innovation is the CO2 Rock Blasting System Technology. This article explores what the CO2 Rock Blasting System is, how it operates, its usage steps, and its significant advantages, particularly in tunnel blasting applications.
