explosive needs to be stored as loading of the truck is integrated with production of the explosive. This implies storing and transport of non-explosive raw materials only. Manufacturing units are available with production capacities from 1,200 tonnes per annum. They are built up by container moduls adaptable for a wide variety of appli cations .
High power blasting agent initiator, which thanks to its Safelock accessory, allows the operation to be safely and agilely primed. Moreover, its plastic packaging protects the explosive blend it contains, allowing it to be more resistant to impact, as well as to the water found in some perforations.
Matrix is gassed chemically to impart sensitivity and adjust the density to performance requirements. Matrix is extensively used in opencast and quarry applications. Gassed Matrix is cream light brown ammonium nitrate blasting intermediate, which is chemically sensitised on the bench to become a blasting explosive. Discover DDS
COURSE DESCRIPTION Rock Blasting and Overbreak Control, Chapter 1 Explosives Engineering. Most raw materials, from which our modern society is built, are produced by the use of explosives in mines throughout the world. The construction of highways, canals and buildings are aided by the use of explosives.
