Date Jul. 17, 1986.The method of geophysical prospecting of polymineral ore bodies including registering pulsed electromagnetic radiation generated by the ore bodies under the action of elastic waves excited in the rock block. The radiation is registered as pulse bursts, each burst corresponding to one ore body. The shape of a pulse corresponding to the ore body under investigation is compared with the shapes of pulses corresponding to ore bodies of the known mineral compositions, and one similar pulse is selected from these pulses. Then a pulse from the burst corresponding to the ore body under investigation is subjected to the Fourier transformation to obtain the pulse height-frequency spectrum of this pulse, which is compared with the pulse height-frequency spectrum of the selected pulse, and when at least two frequencies of the maximums of the amplitudes of these respective spectra coincide, there is established correspondence between the mineral compositions of the known ore body and of the ore body under investigation. |
