There are considered the reasons of low technological and economic efficiency of blasting operations technology with application of patronnered explosives. There was carried out the analysis of modern types of industrial-scale production explosives for the spur breaking of massif. There is stated the carrying out technology and results of ground and industrial testings of manufactured pilot lots. There was estimated the application efficiency of own making granulated explosives. There was defined the range of problems, which solution is necessary for guaranteeing of possibility of application of usage technology of own making granulated explosives on the mines of Priargunsky Industrial Mining and Chemical Union. There was substantiated the urgency of researches of application possibility of emulsion water-worked explosives for blast-hole loading in underground mine excavations.
