摘要

salzgrusversatz for the filling of underground cavities in the salt of rock with an initial permeability of & 10^–11 m², characterized in that the mixture of 70 to 95 mass -% granular mineral salt and a ca - k - mg - containing an additive in proportions of from 5 to 30 mass -%, which leads to the formation of polyhalite.
