Nonex Rock Breaking Cartridges

NoneX™ Rock Breaking Cartridges are used extensively all over the world, for breaking rock, concrete and many other materials expeditiously, with complete safety and without any adverse effects especially in sensitive areas.

PSI Limited have fully qualified and experienced NoneX™ personnel available to complete your project requirements.

Advantages of NoneX™

  • NoneX™ is environmentally sensitive

  • Minimal fly rock

  • Minimal vibration

  • Lower noise and overpressure levels than conventional explosives

  • Can be used underwater

  • Negligible noxious gasses

  • Only localised clearance of personnel is required with NoneX™

  • NoneX™ is safer to transport, store and use than conventional explosives

  • Can be used with low capital, lightweight equipment

How NoneX™ works​

NoneX™ Rock Breaking Cartridges are a chemical rock breaking technology. They have a low blasting impact and can be used in small confined and sensitive areas.

 

The NoneX™ Technology is based on a non-detonating propellant compound enclosed in a cartridge, which reacts very quickly when ignited to produce high volumes of harmless gas, mainly consisting of nitrogen, carbon dioxide and steam.

 

The process commences with a hole being drilled into the rock to be broken, and the NoneX™ catridge is then placed inside those holes.

 

When the cartridge is sealed in a drill hole, the high pressure gas generated by the ignition of the propellant enters into the micro-fractures created from the percussive drilling process and into the natural fractures and planes of weakness of the rock, expanding the fractures and propagating cracks towards the nearest free face of the rock.

 

The number of cracks propagated is related to the maximum pressure and peak pressure rate achieved by the expanding gasses within the drill hole. The gas pressure, within the drill hole and propagated cracks, then causes the fractured rocks to heave apart, producing a shearing of the rock often called splitting.

 

Will it break any size of rock and concrete?

NoneX™ cartridges are available in sizes from 5g to 500g. This allows us the ability to handle all sizes of jobs, from the small rocks to large steel reinforced concrete or bedrock.

 

NoneX™ is also water resistant. It can be used in wet holes, or as a waterproof option in underwater conditions.
