Estimation of mutual influence of close cylindrical chambers

Abstract

Development of rock salt deposits by underground dissolution, as a rule, is carried out by cylindrical chambers arranged on a given (square or rhombic) grid. The calculation of parameters of stable chambers and separating pillars can be approached by the method of continuum mechanics, using, for example, the solutions obtained for vertical mine shafts. However, the continuum mechanics solutions are developed only for single excavations, and their application to the calculation of cylindrical chambers located on a given grid and having a mutual influence makes it necessary to introduce additional conditions.
