Kiyzassky Open-Pit Mine Improves Dust Suppression System

The Kiyzassky Open-Pit Mine has completed the final stage of improving the dust suppression system at its coal loading railway station.

The company has installed a system that reduces dusting when loading coal into wagons on two tracks. Nozzles located above the wagons spray a fine mist so that coal dust settles quickly.  The system is highly efficient, making it possible to process all coal at the loading stage.

This is a unique innovation with no analogues in the country. The equipment has proven its effectiveness, and the system has been put into operation.

The decision to improve the dust suppression system was made in February of 2022 at a meeting attended by the company’s management and local residents to address environmental issues.

The system was installed in several stages. In the first, four water cannons were installed that spray water under pressure to a distance of up to 60 meters, creating a curtain of water that catches and deposits dust. At the second stage, 24 sprinklers were put into operation that irrigate coal stacks.

The new equipment makes the coal loading process as safe as possible for the environment. The phased implementation of the program will have a positive impact on the environment.  There are also five dust suppression plants at the station, as well as a noise- and dust-absorbing screen, 250 meters in length and 10 meters in width. Additionally, 5,000 pyramidal poplars have been planted alongside the station.
