Popis: Large-scale blasting induces Rayleigh waves. It is possible to make these waves interfere and to form their crest by choosing a proper range of blast delays. The positive half-wave propagation over a projected loosening zone of every next detonated shot hole will generate tensile stresses, which will enhance blasting effect.
