Annotation The feasibility of using waste hydrometallurgical processing of uranium ores of Streltsovsky ore field during the laying of underground mine workings is evaluated. One of the perspective directions of mining backfill development of PJSC «Priargunsk Industrial Mining and Chemical Union» is considered. The option of reduction of volumes of tail deposits and utilization of low-active waste with their placement in mine workings is offered. The results of laboratory researches on change of composition of backfill material with use as inert microfiller of tails of hydrometallurgy are presented. The possibility of their application in the development of mining backfill production as a component of backfill material is analyzed. Physicomechanical, rheological and radiation characteristics of backfill material of experimental structure are defined. The compliance of physico-mechanical and rheological properties of experimental compositions of backfill material on the basis of tails of hydrometallurgical processing to requirements imposed to the bookmark given to mine is noted. The possibility of use of the polymeric isolating sealants for the purpose of decrease in an emanation of radon from a surface of the modified backfill material is considered. The efficiency of their application is established. The feasibility study on application of waste of hydrometalturgical processing of uranium ores for a laying of mine workings is submitted. The positive results for carrying out trial works and subsequent implementation of the developed technology on the mines of PJSC «PIMCU» are received
Key words uranium mining enterprise; processing of hydrometallurgical waste; mining and production of filling; backfill material; experimental samples; underground mining; superficial tailings dam; low-active waste; radon; Streltsovsky field
