effect (for coal), the formation of microchannels of electrical breakdown (quartz) and the migratory (interlayer) and/or electron-relaxation polarization of dielectric minerals. Our results show that it is possible in principle to use the nonthermal effect of high-power nanosecond electromagnetic pulses to raise the efficiency of softening and disintegration of rocks and rock forming minerals.
