Annotation:

Bearing strength of interchamber pillars and also width of the rooms sharply decreases under seismic influence of explosive works. To compensate it, they have to increase width of the ore pillars. It leads to growth of losses. It is necessary to develop parameters of explosive works which allow reducing seismic influence on backup abutment.
