PROCESS OF EXAMINATION OF HOLES BY GAMMA METHODS OF NUCLEAR GEOPHYSICS Russian patent published in 1996 - IPC

FIELD: mining industry, geophysics. SUBSTANCE: process is related to examination of holes by gamma methods, namely by method of natural radioactivity of all modifications, by gamma-gamma method, by methods of spectrometry of gamma radiation of inelastic scattering, activation and absorption of neutrons. Geometric factors of intermediate zone and seam are found by values of radial sensitivity of borehole equipment and geometric factor of half-space with allowance for hole conditions of measurement. Correction for radial inhomogeneity of system " device-hole-seam" is entered by geometric factors. EFFECT: increased reliability of process. 5 cl, 2 dwg, 4 tbl
