MINE ROCK CORE SURVEY METHOD Russian patent published in 2013 - IPC G01V8/00 

FIELD: mining.

SUBSTANCE: method involves installation of core on an object table, illumination of its surface with directed flow of visible light band; reception of some part of light reflected from core surface and processing of the received information. Besides, the light part reflected from core surface is directed to a detector for conversion of its wave length and light intensity to a digital format with further transfer of that information to a computer to perform further operation with colour index of core material as per the pre-set complex of programmes providing storage in RGB format (red, green and blue), averaging, conversion of RGB format to HSL format (hints, intensity and brightness), buildup of variation diagrams of parameters of RGB and HSL colours and distribution bar charts of the above colours.

EFFECT: invention allows improving survey accuracy.
