Analysis of cracks development in rock massif with the use of dynamic destruction resistance

The object of research: the process development main cracks in massif rocks under action a wave impulse taking into account dynamic destruction resistance.
 Investigated problem: Description dynamics crack mode increasing their size, as well transition to an unstable growth.
 scientific results: In present article uses approach based on principle least and N-characteristic growth resistance. This allowed obtain analytical equations trajectory rock characteristics process.
 area practical use research considered allows predict formation shear surface quarries natural slopes. also set time-varying probability steady state adjust, if necessary, parameters blasting.
 Innovative technological product: Analytical regularities for driving force resistance are obtained, which take velocity acceleration crack, time nonstationarity load.
 Scope innovative proposed can be used design blasting operations calculation probabilities massifs influence loads.
