We specialise in blasting
work in sensitive environmental areas such as wetlands, nature reserves, inner
city areas and residential areas. We insist on environmentally clean operations
and therefore toxic and other chemical options to break the rock or obstacle are
excluded.
We use NoneX™ Technology that produces low vibration
resulting in significantly reduced damage to surrounding rock and infrastructure;
minimal fly rock; low overpressures resulting in minimal concussion effects;
and minimal fumes and dust allowing operations to be carried out continuously
without the need to evacuate the area as is the case with conventional explosives
blasting.
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. 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.
