Abstract
The paper provides information on the distinctive features of the geological structure of the Starobinsky deposit's formations and the current mining methods used at Levels II and III. Two methods of selective potash mining using the "loading-unloading-dumping" technology are proposed. The economic effect at realization of recommended schemes is calculated.
