Russia’s leading steel maker & miner Metalloinvest’s Mikhailovsky & Lebedinsky GOK have put into operation an automated system for continuous monitoring of water levels in open reservoirs of hydraulic structures. The Company allocated about 28 million rubles for the purchase and installation of new equipment. More than twenty sensors are located in the reservoirs of the GTS of MGOK, and 12 more are located at the facilities of the LGOK tailings facility. Radio wave sensors of the system determine the water level with high accuracy. The data enters a single computer network. Specialists around the clock in real time evaluate the data, the dynamics of the process, make the necessary management decisions.The stability of the entire technological process directly depends on the trouble-free operation of the GTS. The implemented systems of automated remote water level control allow to effectively manage risks by applying preventive measures. Hydraulic structures play an important role in the production cycle of plants: they provide technical water supply, hydraulic protection of the quarry, laying and accumulation of waste from the concentrate enrichment process, and a number of other functions. Exceeding the maximum allowable water level in technological reservoirs can lead to equipment failure, flooding of adjacent facilities and territories. Too low water level can cause the death of fauna in the reservoir and in the coastal area and adversely affect the ecosystem.
