Destruction of Ferruginous Quartzite in Rock Mass by High-Gradient Magnetic Fields

Abstract

The results of experimental and theoretical studies of the applicability of strong pulsed magnetic fields to destruct ferruginous quartzite are presented. A “magnetokinetic” model of ferruginous quartzite destruction, based on the interaction of magnetite grains with quartz matrix at the passage of a high-gradient electromagnetic pulse through rock, is proposed. It is shown that the high-gradient pulsed magnetic field can be used to destruct quartz-containing rocks in a massif during both drilling and blasting and when solving geoenvironmental problems in mining crystalline rocks, complex-structure massifs of ferruginous quartzites by the example of deposits of the Kursk magnetic anomaly (KMA) and others.
