“Corum Druzhkovka Machine-Building Plant (Corum DrMZ), part of the Corum Group (DTEK Energy), has started manufacturing a 200-ton hoist for Metinvest Mining and Metallurgical Group, the plant reported on Facebook.
“Metinvest’s miners have already started preparing a solid and stable foundation on the air supply shaft No. 3 to install the machine,” the statement said.
Installation of the equipment is scheduled for the fourth quarter of 2024.
The plant also reports that in March it produced 34 units of equipment and more than 111 thousand components and spare parts, including trolleys, anchors, fire pipes and high-pressure hoses, under the conditions of relocation. Also, 35 sections of powered roof supports were repaired.
Corum Group is a leading manufacturer of mining equipment in Ukraine and is part of DTEK Energy, the operating company responsible for coal mining and coal-fired power generation within Rinat Akhmetov’s DTEK holding.
“Corum DrMZ, relocated to Dnipro in 2022, earned almost UAH 500 million in net profit last year, compared to a loss of UAH 452.8 million a year earlier, while net income increased 2.7 times to UAH 1 billion 530 million.
“Metinvest comprises mining and metallurgical enterprises located in Ukraine, Europe and the United States. Its main shareholders are SCM Group (71.24%) and Smart Holding (23.76%), which jointly manage it.
“Corum Druzhkovka Machine-Building Plant (Corum DrMZ), a part of Corum Group (DTEK Energy), has shipped a counterweight for the Geroyev Kosmosa mine control room, which will operate in the main shaft of the mine in conjunction with a rock skip, the plant reported on Facebook.
“A counterweight is a large, heavy metal structure designed to balance a cage or skip in a vertical workings. The equipment acts as a counterweight, and its absence makes it impossible to operate the entire hoist,” the statement explained.
The height of the counterweight frame is 10.8 m and the weight of the equipment is about 25 tons.
“A specialized anti-corrosion coating was used in the manufacture of the counterweight, and metal structures and components were improved. We manufactured such modernized counterweights for this mine in early 2018. The average service life of the equipment is 7 years, so the replacement of the counterweight is planned,” explained Sergei Astapenkov, Chief Design Engineer at Corum DrMZ, as quoted in the statement.
The equipment is scheduled to be installed next year.

In January-October this year, the company’s machine builders produced 14 roadheaders and shearers and supplied 931,000 spare parts and components to miners. During this period, according to the company, CorumDrMZ manufactured 285 units of roadheaders (including 2 KPD tunnellers) and 850.4 thousand spare parts and components. Also, 236 units of mine equipment were repaired.
“Corum Druzhkovka Machine-Building Plant (Corum DrMZ), a part of Corum Group (DTEK Energy), whose production site is located in Dnipro after the relocation, has produced 242 units of underground transport this year, fulfilling all orders for the supply of underground transport, having manufactured 242 units.
“After the plant was relocated, we had to re-establish production. Production of underground transport was no exception. However, Corum DrMZ machine builders have managed to cope and have even already fulfilled all orders for the production of trolleys,” the company’s Facebook page says.
In particular, 228 freight trolleys were produced, including 173 units of the most popular VG3.3-900, which can move up to 6 tons of coal; as well as 22 VDK2.5K trolleys designed for 4.5 tons of coal and capable of unloading anywhere without a special unloading mechanism (used in mine construction and during the reconstruction of coal enterprises).
In addition, in the first ten months of 2023, the plant shipped 33 transport trolleys to mines, which are used in mine construction.
“The mines are also updating their passenger car fleet. This year, machine builders have produced 13 trolleys for transporting miners through horizontal mine workings and one for transporting passengers through inclined mine workings with inclination angles of 6 to 30°,” the statement said.
All underground mine transport was made to order for DTEK Energy’s mines.
As reported, the plant produced the first freight cars after the relocation in May this year, having made changes to the design and manufacturing technology of parts and the car in general while maintaining quality.
