Book Description
Excerpt from The Effect of Stemming on the Efficiency of Explosives All commercial explosives owe their power of doing work to the expansive force of the great volume of gas evolved from them at the moment of explosion. The pressure exerted by this gas in the drill hole or other confined space in which the explosion is brought about is what makes explosive substances of value in mining or other industries and is the primary cause of all those manifestations of energy that follow the firing of a charge. Common black blasting powder, on explosion, produces about 390 times its own volume of permanent gases; 40 per cent dynamite pro duces about 530 times its own volume of permanent gases; and nitroglycerin produces somewhat more than 747 times its own vol ume of permanent gases. These proportions of volume of gases to volume of explosive are those that would be found if the gases were measured under normal conditions of temperature and pressure, but at the moment of explosion the gases are highly heated, and there fore tend to occupy a volume much greater than that represented by the figures given above.
