The newly discovered diamond deposit Verkhne-Munskoye successfully completed testing of a new production line for the production of emulsion explosives. This complex is necessary to ensure the drilling and blasting operations at the Magnitny and Zapolyarny open-pit mines.
During the pilot tests, experts created more than 30 tons of explosives on a new modular line. Within the adjustment of the system, an optimal scheme and composition was developed for the production of emulsion explosives.
A modular line for the manufacture of semi-finished industrial explosives is produced in Russia. The equipment is located in several insulated and heated container-type block-modules. This is due to extremely low temperatures in the winter. Low temperatures can drop to -65 degrees Celsius at the Verkhne-Munskoye deposit. Modern automated control system allows organizing round-the-clock production with minimal staff participation.
“The resulting semi-finished products are inexplosive and are made from Russian raw materials under the supervision of a technician. A separate container is provided for each technological stage of the emulsion production. In one module, it is prepared; in the other, it is temporarily stored. The emulsion is pumped into a mixing and charging machine and delivered to the place of blasting production. An explosive is formed directly in the well when the components are mixed by a mixing / charging machine. ALROSA’s own new production line allows to reduce the cost of drilling and blasting at the Verkhne-Munskoye diamond deposit,” said the head of the Verkhne-Munskoye workshop Sergei Rychkov.
The staff working on this module has already passed the necessary training. The daily capacity of the plant is more than 27 tons. A similar plant is successfully operated by the Udachny Mining and Process Division for drilling and blasting operations at the Zarnitsa open-pit mine.
