===Velocity of detonation===
{{Main|Detonation velocity}}
The velocity with which the reaction process propagates in the mass of the explosive. Most commercial mining explosives have detonation velocities ranging from 1,800&nbsp;m/s to 8,000&nbsp;m/s. Today, the velocity of detonation can be measured with accuracy. Together with [[density]], it is an important element influencing the yield of the energy transmitted through both atmospheric over-pressure and ground acceleration. By definition, a "low explosive", such as black powder, or smokeless gunpowder has a burn rate of 171–631&nbsp;m/s.<ref>{{Cite book|url=https://books.google.com/books?id=PmuqCHDC3pwC&pg=PA106|title=History of Shock Waves, Explosions and Impact: A Chronological and Biographical Reference|last=Krehl|first=Peter O.K.|date=2008-09-24|publisher=Springer Science & Business Media|isbn=978-3-540-30421-0|page=106|language=en}}</ref> In contrast, a "high explosive", whether a primary, such as [[detonating cord]], or a secondary, such as TNT or C-4, has a significantly higher burn rate about 6900–8092&nbsp;m/s.<ref>{{Cite book|title=History of Shock Waves, Explosions and Impact: A Chronological and Biographical Reference|last=Krehl|first=Peter O.K.|publisher=Springer Science & Business Media|year=2008|isbn=978-3-540-30421-0|page=1970}}</ref>
