Co2 rock breaking system is a new technology which can replace soundless cracking agency and explosive.
Dinli CO2 rock-breaking system is a new rock-breaking technology that can replace silent rock-breaking agents and explosives. It uses liquid carbon dioxide to absorb heat and gasify, and the volume expands rapidly to generate high pressure, which causes the rock mass to crack. No vibration, shock wave or hazardous gas will be generated during construction. So this method is very safe and convenient. The emergence of this technology perfectly solves the problems of prohibition of blasting in mines and rock excavation, and the low efficiency of silent crushing agents and hydraulic crushing agents! It has been widely used in mining, quarrying, highway construction, building foundation, tunnel excavation and other fields.
Carbon dioxide gas can be converted into liquid under a certain high pressure, and the liquid carbon dioxide is compressed into a cylindrical container (steel pipe) by a high-pressure pump. When the micro-current passes through the electric ignition head, it causes the heating agent to generate high temperature, instantly vaporizes the liquid carbon dioxide, and rapidly expands to generate a high-pressure shock wave, causing the energy release device to open, generating an expansion pressure of more than 300MPA, and instantly releasing the high-pressure gas to cause rock fracture and loosening. Because it operates at low temperature, it does not mix with the liquid and gas in the surrounding environment, does not produce any harmful gas, does not produce arcs and sparks, and is not affected by high temperature, high heat, high humidity, and high cold. It has a diluting effect on gas when it is cracked in a coal mine, without vibration and dust. Carbon dioxide is an inert, non-flammable and explosive gas, and the release process is a process of gas expansion, a physical change rather than a chemical reaction.
ADVANTAGES：No shock wave. There is no vibration. No pollution or dust emissions. No explosives, no hazardous chemicals or fumes.
The operation is simple and quick. Rock-breaking steel pipes are reusable and cost less. Compared with traditional machinery, the output is higher. No need for strict supervision from relevant departments. No tedious approval procedures for explosives are required.
WORK PROCESS： Filling carbon dioxide into rock breaking steel pipe.
Drill holes in rock or concrete to a depth of 2 times the hole spacing.
Insert the rock-breaking steel pipe into the hole.
Plug the holes with a stone sieve or aggregate.
Tamped to form a strong seal, the cartridge will contain gas when ignited.
Clear local area.
Connect and launch.
