Corum’s Record-Breaking Machine Extracts Million Tonnes of Coal at Krasnolymanska Mine

 Corum’s Record-Breaking Machine Extracts Million Tonnes of Coal at Krasnolymanska Mine
22 Сентября 2015

In early September, the UKD400 shearer extracted its first million tonnes of coal in the fourth Northern longwall face of State-owned Coal Company “Krasnolymanska”. This is already the second million mark of the UKD400 this year.

“Amid the crisis in the coal mining industry, when part of the mines was caught up in the area uncontrolled by Ukraine, the importance of the operating mining companies has increased. Along with this, the requirements for the efficiency of mining equipment, its resource and energy efficiency have been tightened, too. Corum’s shearing equipment completely meets the miners’ needs and demonstrates worthy results. For example, this summer, our UKD400 shearer has already extracted a first million tonnes of coal in longwall face No. 26 of DTEK’s Obukhivske Mine Association. Now, the first million tonnes is produced for State-owned Coal Company “Krasnolymanska”, Yakov Sidlyarenko, Corum Group’s CEO, comments.

The standard capacity of the UKD400 is 30% higher that the competitors’ analogues, which provides it with increased efficiency. The capability to fit in the layer and cut rock, which is 15%-25% lower than that of foreign analogues, leads to the maximal increase in the economic efficiency of extraction.

The UKD400 has been operated at Krasnolymanska Mine as part of Corum’s MDM shearing system since January 2014 in the layer with the average extraction capacity of 1.15 meters. Last year, the miners successfully mastered the new equipment and secured the production of over 565 thousand tonnes of coal. In September 2014, the UKD400 helped them make a record of extracting coal from thin layers, 100 thousand tonnes. At that time, the machine broke its previous records made at DTEK’s Chervonyi Partyzan Mine by 20 thousand tonnes. Since the start of 2015, Krasnolymanska Mine has produced 434.5 thousand tonnes more, which resulted in the total amount of 1 million tonnes.


Information about the UKD400 shearer


The UKD shearer is intended for mechanised extraction of coal in production faces with flat-lying and inclined layers with the thickness of 0.85 m to 1.5 m. The Division’s designers made this equipment more mobile in the conditions of narrow production faces: the UKD400 is more manageable and manoeuvrable compared with its predecessors; the major extraction operations can be managed remotely, by means of an entry remote control and by radio signals staying near the machine. Besides, there is a system for automatic diagnostics and control over the state of the units, with indication of the data in the operator’s desk. The equipment is able to extract 2,700 tonnes from 1 meter of a layer per day on average, reaching the maximum level of 4,500 tonnes per day.

The UKD400 shearer is equipped with the state-of-the-art operation and diagnostics system, which enables the operators, the mine dispatcher and remote users to see the current load of electric engines, the travelling speed, the errors fixed by the operation system, the temperature of engines etc. The UKD400’s precision of fitting in a layer enables it to extract coal with the minimum of contaminants.
