The systematic name of this enzyme class is 1,3-beta-D-glucan:phosphate alpha-D-glucosyltransferase. Other names in common use include laminarin phosphoryltransferase , 1,3-beta-D-glucan:orthophosphate glucosyltransferase , and laminarin phosphoryltransferase .
Explosive materials are produced in numerous physical forms for their use in mining, engineering, or military applications. The different physical forms and fabrication methods are grouped together in several use forms of explosives. Explosives are sometimes used in their pure forms, but most common applications transform or modify them.
A mining simulator is a type of simulation used for entertainment as well as in training purposes for mining companies. These simulators replicate elements of real-world mining operations on surrounding screens displaying three-dimensional imagery , motion platforms , and scale models of typical and atypical mining environments and machinery.

In 1990, 2.1 billion kg of commercial explosives were consumed in the United States (12 m 3 per capita), representing an estimated expenditure of 3.5 to 4 billion 1993 dollars on blasting. In this year the Soviet Union was the leader in total volume with 2.7 billion kg of explosives consumed (13 m 3 per capita), and Australia had the highest ...

The composition of the two most common variants differ according to their use. The 1A (or 10) variant is used for mining, and is based mostly on crystalline PETN.The versions 1AP and 2P are formed as hexagonal booster charges; a special assembly of PETN and wax inside the charge assures high reliability for detonating cord or detonator.
The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.
