The innovative Polymetal method has proven effective
A new blasting method using a detonating cord has proven its economic viability. Today, the method is used in production at the Dukat and Lunnoye deposits in the Omsukchan district, as well as at Albazino in the Khabarovsk Territory.
Konstantin Denisenko, a leading engineer of the Mining Planning and Design Department of Serebro Magadan (a subsidiary of Polymetal), suggested using an 80-gram detonating cord (DSHN) instead of explosives. Previously, the DSHN was used only in the subway, and during drilling and blasting operations by the classical method, the quality of the ore suffered in some areas.
The young engineer decided to test the method on open cast mining and presented his idea at the Polymetal research and production conference in 2019. The economic feasibility of the idea was proved at the Terem silver-polymetallic deposit in the Omsukchan district. The results were encouraging: the ability of the cord to crush the rock was higher than the classical method.
“And although the capital costs of the new method increased, the good quality of the ore mined and the reduction in transportation costs blocked the costs,” said Konstantin Denisenko.
His project was approved by the jury and won the nomination "Efficient Production". In May, Konstantin Denisenko will take part in the final of the scientific and production conference “Innovations in Production”, which Polymetal plans to hold in Vladivostok.
