| Popis: | A model of gas-dynamic instability in an explosion channel using the explosive-reactive method for rock destruction is studied. The crack propagation rates and the regions of elastic vibration damping in a massif are determined. A critical amplitude threshold of elastic vibrations the exceedance of which indicates crack initiation in a continuous medium is proposed. |
