The Increasing of the Fractured Ezplosion Effect on Rocks

摘要：

The indicators of the effectiveness blasting effect on rocks can not synonymously defined be means of simple determination of the total energy released during explosives detonation. These indicators depends on intensity released energy and fullness their use on useful forms of the explosion work. The use of the explosion energy on their useful forms depends not only on explosives properties, but also mechanical rock properties and rock strength. To increase the blasting fractured effect as pointed in 1 it is necessary use explosives with velocity of detonation closed to acoustic velocity in fractured media.
