Abstract
A new mechanism of deformation of enclosing rocks near mine workings is presented. The developed method to calculate geomechanical behavior of rocks takes into account the weight of overlying strata in the concordant direction with the orientation of tensile stresses at the mine working boundary while these directions differ in the mine working floor. The proposed calculation method for rock deformation includes two additional parameters characterizing the ratio of displacements in the mine working roof and floor and the ratio of the ground surface movement to to the mine working roof displacements which are determined experimentally.
