Our cartridges break rock and concrete with low ground vibrations, controllable fly rock, reduced dust and noise and will only require localised clearance of equipment and personnel. The Nxco cartridge technology is based on a non-detonating chemical compound enclosed in a cartridge which reacts quickly when ignited to produce high volumes of harmless gas that mainly consists of nitrogen, carbon dioxide and steam. The cartridge is confined in a drill hole by means of stemming and when ignited generates a large volume of gas. This gas enters into the micro fractures created by the percussion drilling process, natural faults and weaknesses of the rock, resulting in the rock splitting due to tensile stresses.
Nxco cartridges are available in 13mm, 28mm, 34mm, 42mm, 60mm and 90mm diameters.
