Abstract
Abstract Blasting is one of the main methods of rock destruction and accounts for approximately 20% of the cost of mining operations. Given that the efficiency of the explosion for crushing does not exceed a few percent, it becomes obvious that further improvement of explosive destruction is necessary, taking into account the new achievements of science and technology. One of the main ways to improve the efficiency of underground mining is to improve the conduct of drilling and blasting operations with the use of the stemming plays a significant positive role in the operation of the explosion.
