Kyshtym deposit of high-value granular quartz is virtually the only source of raw materials for high-tech sectors of the Russian economy. Currently, the deposit is developed by underground mining with blasting. The applied technology of drilling and blasting operations using of packaged explosives, manual charging and tamping clay laborious and does not provide the required parameters of output and oversize overgrinding quartz fraction -20 mm. Consequently, actual improvements in technology and the optimization of the parameters of blasting operations. The technology of breaking with vertical bores and using mechanized charging granular explosives and lump blasting of all the charges made. As shown by theoretical studies and laboratory experiments, the degree of reduction in the breaking of overgrinding quartz can be achieved through the use of the synergies of the charges at their simultaneous blasting holes, the result of which is the formation of a common cavity explosion without overgrinding zones around each charge. Based on the results of theoretical research and laboratory experiments, mathematical simulation of blasting parameters for the proposed development of the industrial implementation of the pilot site Kyshtym deposits.

The study has been supported by the Ministry of Education and Science of the Russian Federation, Unique Project Identifier RFMEF160714X0026.).
