Study of Shock Wave Propagation in Fractured Massifs during Operation of a Portable Explosive-Reactive Complex

Abstract

The results of modeling shock wave propagation in a fractured rock massif during explosive-reactive drilling are presented. The features of the fracture process in the case of tight contact of structural elements of the massif and in the presence of air-filled fractures are investigated. The interrelation of shock wave velocities with the velocities of passed and reflected waves on inhomogeneities in the rock massif, velocities of displacement of medium particles, and the size of the fracture zone is estimated.
