Rock Breaking Solutions Australia - Non-Detonation Blasting Equipment for the Mining Industry

Rock Breaking Solutions Australia is a non-detonation blasting company specialising in mining, quarry and civil construction works. We provide a national service with professional and experienced staff. Our goal is to provide a personal and specialised blasting alternative and we pride ourselves on providing cost effective solutions along with expert knowledge to provide a safe and efficient working environment.

Non-detonating technology

Our Nonex™ technology is based on a non-detonating chemical compound, enclosed in an all integrated cartridge that reacts very quickly when it is triggered, producing an elevated volume of non-noxious gas, primarily composed of nitrogen and carbon dioxide.

When the Nonex cartridge is hermetically closed in a hole, the gas creates pressure on the sides of the hole and produces a breakage of the rock or cement; such breakage is often called breakaway. The Nonex cartridge use of a patent technology that increases the transfer of energy to the inside of the rock or cement to enhance the effectiveness of the breakage.

Secondary breaking and slyping for above and underground mines

Using Nonex cartridges for secondary breaking during load and haul activity is feasible, safe and productive. Most open cast sites have large excavators, some of which have outlived their productive life, but make excellent support tools in the secondary breaking process. Material handling support for drilling, putting the oversize into manageable rows provides easy access to the rock and enhances safety. The same excavator loads the broken rock for removal.

Rock breaking for crusher blockages

Rock poppers are 12mm - 13mm diameter cartridges, drilled using 14mm - 16mm diameter drill bits about 400mm long. Using a rechargeable drill will allow you to access tight areas like crusher jaws. When oversize rock becomes stuck in the crusher jaws it can become a costly and time consuming exercise. The problem can be easily solved by with an operator using a rechargeable hammer drill and the Nonex 1013 Rock Popper.

Demolition of reinforced concrete

Experienced contractors worldwide know that it is a challenging task to drill through the reinforcing grid, which is designed to support high Mpa concrete, which clings onto the reinforcing steel bars as the design intended.

Nonex allows you to crack the concrete, then use mechanical means such as an machine mounted hydraulic hammer or a heavy-duty, pneumatic pavement breaker to remove the cracked concrete. This is an almost impossible task unless the concrete is first cracked.

Mass breaking for mine sinking shafts

Nonex can be used to do mass breaking, including shaft sinking, through the application of a specific methodology. The pressure of expanding gasses breaks rock in tensile > the free face burden. A mass break is created when multiple holes are drilled vertically and charged with a large number of heavily charged cartridges such as 500g x 60mm diameter Nonex 50060 (drilled using a rig).

The free face becomes the surface cap above the charged holes. Depending upon the nature of the rock, it is feasible to drill to a depth of 2m with spacing of 1m, charging up to 300 holes, on a bench 40m x 7.5m with 300 x 500g cartridges initiated simultaneously produces 150,000l of gas, which must go somewhere. This combined volume of gas takes off the cap, shattering it into small particle sizes. Noise and fly rock is controlled by a layer of conveyor belting mats over the charged bench and up to 2m of earth cover on top of the mats.
