FIELD: mining.
SUBSTANCE: anticipatory probing of rock mass is performed with geophysical methods to drill reference geological survey wells with increased range compared to normative one. Geological survey wells are drilled. Core material is investigated. Contour of ore deposits is reproduced. In crosswell space further probing of rock mass is carried out with geophysical methods from surface or from mine workings. By comparative analysis of core material research with geophysical analogs, it is decided on accuracy of ore deposits contour reproduction.
EFFECT: reduced scope of well drilling works, minimisation of minerals losses in protective pillars, improved ecological compatibility due to provision of high reliability of water-bearing horizons hydraulic insulation.
