Today, experimental measurement of the shock energy / gas energy pair, or pool test, has now become virtually standard. But the energy of the pool per m (exp 3) of bedrock is of no importance for explosives used in any means other than water. This is why the notion of energy dissipated according to the firing conditions must be defined by:
* The conditions for the activation of explosives
* The characteristics of explosives
* Trigger geometry
* The mechanical characteristics of the rock
The formulation of physical phenomena as equations helps to study how one parameter influences others.
The quantification of the dissipated energy can accurately estimate the results of the shots in advance based on the data on the shots or, conversely, determine the shot plan based on the desired result.
The definition of shock energy and gas gives only a synthetic view of the effects of the shot. In addition, knowledge of the origin of these effects helps explain and compute the most common mining phenomena, that is, decoupling, “death by compression”, “air decks”, shooting with moderate effects, calculation of damage , etc.
