The main feature of underground mining method at potassium and salt deposits is protection of mining operations from penetration of fresh waters. It can be achieved via usage of chamber working system that should provide solidity of above-laying waterproof rock pack, named also in mining practice as waterproof stratum (WPS). The main components of geomechanical provision of protection of potassium mines from flooding, including presenting definitions of mechanical parameters of salt rocks for different loading conditions, natural tool measurements, mine-surveying observations on land surface deformation, results of geophysical investigations are observed. This information makes parametric base of theoretical analysis of the processes of WPS deformation and destruction. It is shown that quality of geomechanical provision of safety of mining operations at potassium mines and of their protection from flooding is directly connected with usage of up-to-date methods of mathematical simulation of stress-strain state of mining technical objects and with completeness of usage during realization of total complex of experimental data - laboratorial, nature instrumental and geophisical ones.

Work is carried out with support of integration project 12-I-5-2050, project 12-P-5-1007 “Problems of stability of the structure-heterogeneous elements of the mining-technical systems”, grant RFFI 11-05-96020 р_урал_а.
