Nonex

Nonex
The Nonex system has undergone extensive research and development in the UK and Spain. In the UK it has a niche market for particular use in slate mines where it is necessary to keep large slabs of the rock intact, and also for the breaking and removal of slate from within the mine shaft. The Nonex system consists of a cartridge which contains a propellant which when ignited produces high volumes of harmless gases such as nitrogen and carbon dioxide are released, providing a pressure increase when the cartridge is sealed in a drillhole. Nonex is particularly suited in situations where the rock is not required to be fractured, but rather, split as it does not cause the rock to shatter. Nonex is classified as a 1.4S pyrotechnic rather than as an explosive. This has a major impact on insurance premiums and they are much lower for sites which use Nonex exclusively over conventional explosives. The product is electrically initiated, and the ignition system is built in to the cartridge. The product is water resistant, which is another advantage over many conventional explosives.
