Corum Group has launched a cutting-edge header, RH160. Designed for crushing particularly hard rock, the machine also has the bolt anchorage equipment. National and international mining companies have already shown their interest in the novelty product. Corum presented the machine and two upgraded shearers, CLS450 and КА200, at Kharkiv-based Corum Svitlo Shakhtaria on 28 February.
RH160 header is a response of mechanical engineers to Ukrainian miners' needs for more powerful and highly resourceful heading machines. The header is designed to crush and load rock when making new tunnels. It can crush particularly hard rock of up to 110 MPa. The machine has another novelty, a built-in bolt anchorage unit, that helps miners to support tunnels with bolt anchors instead of framing. The new solution is more reliable, faster, and cheaper. Crucially, it can make the work of shaftmen easier and safer. The new machine is run remotely with mobile control stations connected to both wire and wireless technologies. Ukraine has no alternative to the solution. The header weighs 55 tonnes.
"Our mechanical engineers look for effective and efficient solutions all the time to enable miners to ramp up heading operations and coal output. This is crucial to ensure our country's energy independence. The new machines embody advanced innovations developed by Ukrainian mechanical engineers to ensure safe and accident-free operations of miners," stated Mykhailo Potapov, acting CEO of Corum Group.
RH160 stands out with its modular operating member where the header can have cutting heads mounted either in line or perpendicularly without the need to replace the operating member. The electric motor power is 160 kW.
"Our company's engineers came to the idea of RH160 as far back as in 2013," said Oleksandr Udovichenko, Corum's Heading Equipment Manager. "We have been developing RH160 in reliance on our extensive expertise and advanced solutions of foreign manufacturers. This synergy has resulted in an unprecedented solution that will pioneer the next generation of medium to heavy-duty headers," he went on to say.
The new RH160 is to undergo industrial tests at Stepna Mine operating under the umbrella of Pershotravenske Mine Group, DTEK Pavlohradvuhillia. Following successful testing, Corum Group will launch mass production.
Along with the heading equipment, the company has presented two upgraded shearers, CLS450 and KA200.
The CLS450 shearer is a cutting-edge equipment designed to cut coal from thin and medium coal beds with a varying thickness of 1 to 2.4 metres. Based on the best achievements of global engineering, it was manufactured in cooperation with DTEK. This is No. 3 shearer of this model. No. 2 and 3 shearers have been operating at DTEK Dobropilliavuhillia Mine Groups since 2017. Model No. 3 is going to cut coal at Almazna Mine in Dobropillia. Compared with earlier models, it has a retrofitted hydraulic system, enhanced component protection, and upgraded electrical equipment. Among the advantages of CLS450 shearer are its high productivity, automated process control system, ability to operate in a complex landscape, and affordable maintenance. Corum Group plans to introduce the shearer to international markets.
The rebuilt and upgraded KA200 coal cutter operating at Blahodatna Mine, Heroiv Kosmosu Mine Group managed by DTEK Pavlohradvuhillia, will have a new chainless operating member, КBТ200, to increase the lifespan of the shearer. To boost its productivity, Corum's engineers equipped KA200 with rakes to pick up the remaining coal and load it onto the conveyor. This will make the work of miners significantly easier, because they had to do this manually.
Corum Group, a part of DTEK energy holding, is a separate engineering business under DTEK Energy's umbrella. Corum Group is the biggest producer of mining equipment in Ukraine.
Corum Group operates heavy engineering assets of System Capital Management financial and industrial group. The following companies operate under Corum's umbrella: plants in Kharkiv, Druzhkivka and Kamensk-Shakhtinsky, Corum Shakhtspetsstroy, Corum Source and Corum Repair service and maintenance companies, as well as trading companies and representative offices. Key clients include 14 largest mining groups owning 150 mines and open-pit quarries. Corum's equipment is used by mining companies in 15 countries.
