DETERMINATION OF INITIAL (NATURAL) VOLTAGES ROCK MASS IN THE STRELTSOVSKY AND ANTEY DEPOSITS
Nowadays and in prospects the task for JSC " Priargunsky Mining and Chemical Organization" is to maintain the volume and profitability of uranium production in terms of its declining trend in the residual ore reserve and increasing the share of low-power ore extraction to the extent the deepening of mining. In the modern market relations the mining of base ores deposits, composing 20% of total reserves, by non-traditional physicochemical geotechnology of block situ leaching of uranium is a perspective direction, expanding the raw material base of the enterprise. For developing the mineral deposits the important scientific and technological task is to determine the initial natural voltage of the rock mass, on the basis on which the parameters of construct elaboration system and timbering mine working are calculated. This article presents the measurements results of the original natural voltages rock mass in the Streltsovsky and Antey deposits, which are recommended to use for drafting of physicochemical geotechnology block situ leaching (ISL) of uranium and for justification ways of mountain pressure managing.
