Abstract
The paper contains the results and analysis of the formation of stress-strain state in blocky structure enclosing the dividing mass. The regularities were established on the influence of blocky structure undermining on stress state of the floor of dividing mass. Recommendations are given for the safe mining in the dividing rock mass.
