Abstract
The basic research aimed to substantiate implementation of ideas and principles of converging engineering and biological sciences in the sphere of mineral mining is accomplished. A methodological concept is proposed to create a convergent technology for underground mining of thick ore deposits. The design features of a new frame-type technology are discussed and the efficient procedure of extracting ore panels is justified. Numerical modeling of stresses and elastic strains at the boundaries of stoping blocks is carried out at various criteria of rock mass disturbance.
