Abstract
Abstract To reduce the frequency of man-made disasters it is recommended to use development of deposits systems with backfilling of working space at potash mines. The use of halite enrichment waste in the filing mixture is proposed in order to improve the technical and economic indicators of the mine and the environmental situation in the mining area. The factors influencing the choice of development technology with artificial maintaining of winning area are considered. The advantages and disadvantages of using the technology of the backfilling are indicated. Aspects of preparation of hardening backfill and questions of improvement of its quality by disintegration activation of components are revealed. The possibility of activation of halite enrichment waste used as an inert aggregate in disintegrators is considered.
