Rich ores have been being excavated in the course of more than 40-year-old exploitation of Streltsovskoe ore field deposits. Nowadays, the rest reserves of deposits include crude and poor ores. Physical and chemical geotechnology (method of block underground leaching) can be the prospective direction, making possible to carry out the efficient development of poor ores at the created situation. By the example of development of certain block of "Glubokiy" mine, there were carried out the calculations, which show, that during the block underground leaching, the cost price of obtaining of final products is by 30% lower in comparison with the traditional technology: horizontal layers with solid stowing with 70% of uranium extraction from the stored ore in underground leaching block.

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.
