Effects of blast pressure on structures and the human body

The following table 1, based on Department of Defense data from Glasstone and Dolan (1977) and Sartori (1983), summarizes the effects of increasing blast pressure on various structures and the human body.

This data originates from weapons tests and blast studies to assess the effect of blast overpressure on structures and people.

This data provides some guidance on the possible effects of mine explosions on miners.
