Corum Druzhkivka Machine-Building Plant (Corum DrMZ), part of the Corum Group (DTEK Energy), has completed the manufacture of a powerful main ventilation fan for the Pavlogradska mine, the plant announced on its Facebook page.
The plant notes that the fan’s impeller has a diameter of 3 m and weighs 26 tons. For comparison, it cites the parameters of the aircraft engine of the world’s largest aircraft, the An-225 Mriya, which has a diameter of 2.33 m and weighs 5.7 tons.
“The fan is 14 m long and over 4 m high and wide. Due to its size, final assembly will take place at the customer’s site, while only partial assembly has been carried out at the plant,” the statement said.
Korum DrMZ notes that this is the fourth fan of this type it has manufactured since 2014 and the third since the company’s relocation.
The cost of the equipment is not disclosed.
According to YouControl, Korum DrMZ, which was relocated to Dnipro in 2022, reduced its losses by 30% in January-June this year compared to the first half of 2024, to UAH 49 million, while its net income fell by 16.8% to UAH 521.6 million.
Corum Group is a leading manufacturer of mining equipment in Ukraine. It is part of DTEK Energy, an operating company responsible for coal mining and coal-fired power generation within Rinat Akhmetov’s DTEK energy holding.
DTEK Energy’s machine builders manufactured and repaired 2,050 pieces of mining equipment in January-August this year, including six new roadheaders, according to the company’s press release. In addition, 1.7 million spare parts and components were manufactured.
“We continue to consistently strengthen the reliability of thermal power generation in wartime conditions,” DTEK Energy CEO Alexander Fomenko is quoted as saying in the statement.
The press release notes that the company’s machine builders have recently begun serial production of Ukrainian electric motors for GSO, which completely replace expensive imported equipment.
The new motors, with a capacity of 75 to 200 kW, are designed for cleaning combines, belt conveyors, and pumping stations.
“They have already received certificates for climate compliance and explosion protection. In terms of quality, they are a full-fledged analogue of expensive foreign equipment. But now they are Ukrainian and more affordable. This result is the culmination of three years of work by machine builders,” the statement said.
As reported, in the first half of 2025, DTEK Energy invested UAH 2.9 billion in Ukrainian coal mining, and in 2024, investments in Ukrainian mines amounted to about UAH 7.5 billion, and over the last three years (2022-2024) – UAH 18 billion.
Since the beginning of this year, DTEK Energy miners have put seven new coal seams into operation. DTEK Energy provides a closed cycle of electricity production from coal. The company’s installed capacity in thermal generation as of January 2022 was 13.3 GW.
A complete production cycle has been created in coal mining: coal extraction and enrichment, machine building, and maintenance of mining equipment.
In January-July of this year, DTEK Energy’s machine builders manufactured and repaired 1,992 units of mining equipment, including four new combines for mining operations, according to a press release from the company.
In addition, 1.4 million spare parts and components were manufactured.
As reported, in the first seven months of 2024, machine builders manufactured nine combines and 618,000 spare parts for mines.
“DTEK Energy’s machine builders continue to be a reliable source of important equipment for Ukrainian mines. Thanks to their work, coal mining companies can operate more reliably, maintain production, and energy companies can more confidently get through summer peak loads and prepare for the upcoming heating season,” said DTEK Energy CEO Alexander Fomenko, as quoted in the report.
As reported, in the first half of 2025, DTEK Energy invested UAH 2.9 billion in Ukrainian coal mining, while in 2024, investments in Ukrainian mines amounted to about UAH 7.5 billion, and over the last three years (2022-2024) – UAH 18 billion.

A complete production cycle has been established in coal mining: coal extraction and enrichment, machine building, and maintenance of mining equipment.
In January–June 2025, DTEK Energy allocated UAH 6.9 billion to preparations for the 2025/26 heating season.
“Key areas include repairs, restoration of thermal power plants, and support for Ukrainian coal mining,” the company said in a press release.
In particular, as noted by DTEK Energy, given the challenges of the war and the consequences of numerous massive attacks on energy infrastructure, the energy holding company is continuing its ongoing repair campaign at thermal power plants. In six months, about UAH 4 billion has already been allocated for this work, which is more than in the whole of 2024, making it possible to prepare generating capacities for winter and maintain the reliability of the power system.
At the same time, intensive preparations are underway at Ukrainian mines. The company’s own investments in coal production since the beginning of the year amounted to UAH 2.9 billion. As a result, in the first half of the year, DTEK Energy miners put seven new coal seams into operation, providing fuel for heat generation.
The company’s machine-building enterprises are also working to support the mines. In the first half of the year, they manufactured and repaired 1,707 pieces of mining equipment, including four new roadheaders, as well as 1.2 million spare parts and components.
“Our power engineers, repair workers, miners, and machine builders continue to work hard to provide Ukrainians with electricity, especially during summer peaks in consumption, and to lay a more reliable foundation for thermal power generation during the next heating season (…) We are continuing to repair and restore thermal power plants, investing in coal mining and providing mines with the necessary equipment,” said DTEK Energy CEO Alexander Fomenko.
According to the company, since the start of the full-scale war, the Russians have launched 205 strikes on DTEK Energy’s thermal power plants. Last year alone, there were 13 large-scale attacks on Ukraine’s energy infrastructure.
Since February 2022, 56 power plant workers have been injured and four people have been killed in attacks on DTEK Energy’s thermal power plants.
