Improving of seismic safety of rocky deposits underground mining is an important scientific and social task. Among possible methods of its solving, application of new explosive materials occupies an important place. Main scientific and practical results of the study in this area presented. An analysis of previous studies and control observations, instrumental measuring of an explosion seismic action by devices and apparatus accomplished. It was shown, that seismic safety improving and efficiency of explosive work at mines increase reached by intensification of technological processes with application of high productivity selfpropelled and small-size charging machinery of new generation, such as machines of ЗЭВС-1 model and portable chargers of ЗЭП15 model, used for explosion operations mechanization. Application of pouring ecologically clean trotyl-free emulsion explosive materials of “Украинит-ПП-2” (Ukranit-PP-2) type also favors to the improving of seismic safety. Their characteristics and purpose presented, peculiarities of application considered. Analysis of methods and technical means for seismic measurements accomplished. Elaboration of seismic monitoring system with application of state-of-the-art automation systems and electronic seismographs proposed, that will allow decreasing level of seismic action on buildings and constructions in an explosion action zone down to requirements of seismic safety standards.
