Abstract: Specific hydrogeological conditions of the Kaliningrad region impose certain requirements for the development of deposits of polymineral salts in order to ensure technical and environmental safety of the process. Taking into account serious prospects in the development of a number of polymineral deposits in the region until 2023, it is crucial to find out development technologies for reverse backfilling of ore bodies in the developed space. The article overviews modern technical, technological, organizational and management approaches to reduce risks in the development of deposits of polymineral salts. The issues of maintaining the integrity of the waterproof layer and minimizing risks of cracks during backfilling process are analyzed. Evaluation of optimal application of backfilling technology in conditions of the Kaliningrad region is presented, issues of allocation of equipment, management of technological process are observed, problems of quality of production, transportation and laying of the mix are examined.

Key words: deposits of polymineral salts technology of backfill process control optimization of transport schemes
