Mining/Quarrying Applications

Originally developed for safe use in fiery coal seams, the Cardox System is extensively used to mine coal, ore and extract dimensional stone.

Cardox was originally developed for safe excavation and mining of coal in underground fiery coal  seams and today provides the same benefits for a safe alternative to explosion.

 

• The Cardox System was initially designed to address the challenges of safe excavation and mining in underground fiery coal seams.
• These coal seams are prone to explosions due to the presence of flammable gases.
• The Cardox System was developed as a safer alternative to traditional explosive methods.

 

Mining and Quarrying Applications:

 

• Coal Mining: The Cardox System is extensively used in coal mining operations. It allows for safe excavation and breaking of coal without the risks associated with explosives.
• Ore Mining: Similarly, the Cardox System is employed in ore mining processes. It aids in extracting valuable minerals and ores without endangering workers.
• Dimensional Stone Extraction: Quarries that extract dimensional stone (such as granite, marble, or limestone) also benefit from the Cardox System. It ensures safe and controlled removal of stone blocks.

 

How Cardox Works:

 

• The Cardox System utilizes high-pressure carbon dioxide (CO₂) stored in specialized cartridges.
• When triggered, the CO₂ is rapidly released into a confined space (such as a coal seam or quarry).
• The sudden expansion of CO₂ creates a powerful force that breaks rock, coal, or stone without causing explosions.
• It’s a non-explosive method that minimizes risks to workers and equipment.

 

Benefits:

 

• Safety: The primary advantage of Cardox is its safety. It eliminates the hazards associated with conventional explosives.
• Precision: Cardox allows for controlled fracturing of rock or coal, ensuring minimal damage to surrounding areas.
• Efficiency: It speeds up excavation processes while maintaining safety standards.

In summary, the Cardox System provides a safe and effective solution for mining and quarrying

Cardox activations can be used where explosives were prohibited due to:

• Fear of nitrates penetrating underground spring and walls
• Shock waves and vibration effecting surrounding houses, shops & roads
• High noise levels
• High dust levels

Hydraulic rock breakers were not considered due to:

• The considerable duration to break the granite
• Exorbitant costs involved
• Increased and continuous noise

This CARDOX system is used in rock excavation or concrete demolition in locations (terrestrial or underwater) where the use of explosives is not possible or application of machinery (hydraulic hammer) is not recommended.
The working principle of the CARDOX system is based on the instant conversion of liquid carbon dioxide to gas. The liquid is contained in steel, reusable tubes, which are drilled into the material to be broken or demolished.
The use of the CARDOX system is absolutely controlable, whereas:
It doesn't cause vibration even in distance of a few meters awayIt doesn't create cracks beyond the working areaIt doesn't create excessive material eruptionIt doesn't cause dangerous gas emissionTypes:
CARDOX rock/concrete breaking system in civil works, quarrying & mining projects, as well as underwater excavations
