The paper presents the results of combination of geomechanical and geophyisical monitoring. The stress state of the minable coal seams is calculated according to the program FAULT3D with account of mining operations plan, specific seam occurrence and geological disturbances. The analysis of seismic events in the geodynamically hazardous zone has been made.
