摘要：The factors affecting the energy explosion loss on rock crushing on con-tact with explosives have been established. This makes it possible to substantiate ways to increase low explosion efficiency. Theoretical estimates of the explosion energy losses during the rocks destruction have been carried out taking into account the explosives properties and heterogeneities in the rocks structure. It has been established that homogeneities in the form of mineral grains of various strengths determine the mechanism of their destruction and crushing during blusting. A thermodynamic loss has been estimated during the expansion of gaseous detonation products, on which the maximum explosion work depends. These losses characterize the theoretical possibility of the transfer of energy stored in an explosive into mechanical work. The explosion losses associated with the origination of shock waves in rocks are also have been determined.
