RESEARCH OF TECHNOLOGY PARAMETERS OF UNDERGROUND MINING OF GRANULATED QUARTZ
The results of research aimed at reducing the high losses of granulated quartz at the Kyshtym mine are presented. Technological paths have been established for a cardinal increase in the yield of conditioned raw materials for underground mining. Theoretical and experimental studies of the parameters of underground geotechnology in the natural conditions of the mine were carried out. The developed version of the combined mining system and the method of blasting a flat system of dispersed charges made it possible to reduce the loss of high-value raw materials by more than twofold compared with traditional technology.
