Abstract
The paper deals with the issues of increasing the efficiency of drilling and blasting operations in difficult mining and technical conditions at underground mines through the use of non-electric blasting initiation means - SINV-SH and vertical concentrated charge stripping technology. The results of research for the mines of the Khakassia Mountain Shoriai are given.
