Abstract
Improvement of efficiency of mining production is directly connected with increase of a degree of use of extracted from a subsoil both the basic and jointly developed or by-product minerals. Application of mass explosions at open-cast mining causes the necessity to protect the sites of jointly developed or nearby deposits from harmful seismic-explosive effects.
