Comparative analysis of blasting quality under different charging methods in waterlogged conditions (on the example of the Pervorechenskoye andesite deposit)

The application of emulsion explosive in the development of deposits by drilling and blasting method in the Primorsky Krai is considered. Special attention is paid to the methods of charging this substance, their efficiency and influence on the quality of drilling and blasting operations on the day surface. The methods of charging wells are described, including mechanized, using a mixing and charging machine, and manual. Features of each method, their advantages and disadvantages, influence on the final result of drilling and blasting works are discussed. A comparative analysis of the quality of blasting at manual and mechanized charging of watered holes in open pit mining operations is carried out. The results of research can be useful in the practical activities of mining enterprises, in scientific developments aimed at improving the technology of drilling and blasting operations.
