This article gives the information about mineral raw materials base of Streltsovskaya group of deposits. There is proposed the technology of processing of low-powerful poor balance and off balance uranium ores by combined method, including underground mining of mineral resources and X ray radiometric ore sorting in underground conditions with separation of waste rocks, rich and poor ores. Rich ore is supplied to the surface with following delivery to hydrometallurgical processing stage. Poor ore is being leached in the structures, which are formed during the block reserves mining. Rock is also situated in the waste area as a stowing material. Usage of the proposed technology makes it possible to do the following operations:

— increasing of operation efficiency of enterprise due to increasing of total output and decreasing of capital and exploitation costs for extraction and processing;
— increasing of reserves provision level;
— improvement of ecological situation of region by decreasing of dump constructions.
