HIGH SPEED VOD/DATA RECORDERS
Velocity of Detonation (VOD) is the speed at which the shock wave front travels through a detonating explosive. VOD is cited by explosives manufacturers for any given explosive under any given condition. The VOD of an explosive is dependent on the explosive’s characteristics such as formulation, density, particle size, diameter, and degree of confinement. It is also dependent on factors affecting those characteristics such as ingress of water or other impurities, static pressure, and dynamic pressure.
Why is VOD Important?
VOD influences how the energy is released from the explosive as a combination of shock energy and heave energy. This affects the fragmentation and throw of the blasted rock and the cost to the mine of mineral extraction.
How is VOD Measured?
MREL provides the means to easily record the actual VOD attained by the explosive anywhere along the length of the explosive column.
What is VOD? 0:30
Being one of the most important characteristics to classify an explosive, Velocity of Detonation is defined as the speed of the detonation wave as it travels through the explosive column.
Why does VOD need to be measured? 1:35
The VOD needs to be measured to let you know the real performance of your explosives in the field, such as corroborating the energy that was supposed to be delivered to the rock.
Who needs to measure VOD? 1:16
Anyone whom is manufacturing, selling or consuming explosives should measure VOD in order to know how the product is performing in situ.
