Method of absolute measurements of volumetric weight of rocks and ores by gamma ray attenuation in a wide beam

Abstract

Determination of the volumetric weight of rocks and ores by gamma ray attenuation in them is performed in situ without disturbing the structure, natural moisture regime, etc. This automatically takes into account macro- and micro-cracking, cavernousness and other features of the structure and texture of rocks and ores. Determination of the volumetric weight of rocks and ores by attenuation of gamma rays has undoubted advantages over other methods: simplicity, high productivity and cost-effectiveness.
