Abstract
The article discusses geomechanical justification of undermined ground evaluation methods. The proposed method of subsidence assessment allows analyzing influence of underground mining on ground surface in development of horizontal and flat-dipping uniform and interstratified beds with different deformability. The predictive assessment procedures for the subsidence trough profile in case of uniform and interstratified rocks are presented.
