The present work suggests and substantiates potassium seams mining technique in conditions of Verkhnekamskoye
deposit. According to the experience of mining at the deposit, sections with accelerated surface subsidence, which
constitute a danger of waterproof mass discontinuity, generate in some cases as the result of technological interbed
space breaking when mining two or more beds without laying stopes. In this regard the technology of reserves winning is
developed, the application of which will allow eliminating the influence of technological interbed space on the process of
removing stopes by means of timely filling the developed chambers with stowing. The realization of the given technology
will allow providing safe exploitation of potassium salts at Verkhnekamskoye deposit, and forecast the development of
shear process at underworked areas with a more accuracy.
Key words: Verkhnekamskoye deposit of potassium salts; chamber system of mining; breaking of technological interbed
space; surface subsidence; stowing.
