Rock Mechanics in Salt Mining

M.L. Jeremic

A study on rock mechanics in salt mining, this work includes coverage of the exploration and opening of salt mining, deformation and failure of the salt, strata mechanics and control for different mining systems, and stability analyses of the mine structures.
