CO2 rock blasting system is a set of machine to use in rock blasting,rock demolition,quarrying,tunnel,underground explosive and so on.

Developed over 60 years ago for use in explosive coal seams in the UK,This technology is mature in Chin. the Gaea CO2 rock blasting system(rock hole drill) consists of a high-strength, reusable steel tube filled with liquid carbon dioxide, a chemical energiser, and a rupture disc. When the Gaea CO2 rock blasting tube tube(rock hole drill) is ignited, the carbon dioxide is almost instantaneously converted from a liquid to a gas. 


Pressure is released from the gaseous CO2 up to 300mpa (3000 bar), it expands through microcracks and fractures the rock. The pressure can be regulated between 1200 and 2800 bar by using rupture disks. Figure 1 shows a schematic diagram of the components which make up the cartridge. The body is filled with liquid CO2, a safety heater inserted in the firing head, a rupture disk in the discharge end of varied thickness to regulate pressure.


 A nylon collar is used to hold the cartridge in place so no stemming is required. The chemical energiser is activated by a small electrical charge which causes detonation(dexpan rock breaking).
