Corum Presents New Design of Powered Roof Support to Mining Market at the Fair in Katowice

 Corum Presents New Design of Powered Roof Support to Mining Market at the Fair in Katowice
14 Сентября 2015

At the International International Fair of Mining, Power Industry and Metallurgy “Katowice 2015”, Corum Group presented the most promising product positions for the Polish market – the KPD heading machine and shields of powered roof support developed under the new project, using advanced engineering solutions.

“The Polish market is one of the key ones for Corum Group. The coal mining industry of Poland intends to develop thin beds, and a hundred years’ experience of our Company in manufacturing specialised equipment is in demand here. We have brought sections of powered roof support to the Fair this year. Powered supports are the basic component of the longwall face system, which should interest the Polish miners by its efficiency. Nowadays, some mines apply ploughing technologies to develop thin beds, but, with the similar extraction volumes, the longwall face systems are more efficient, as their use enables to reduce the miners’ expenses by 1.5-2 times”, - Yakov Sidlyarenko, Corum Group’s CEO, says. 


Shields of powered roof support type L 061/15, demonstrated at the trade fair, were developed by Corum’s engineers under the new project and have increased resource parameters and mounting speed. Due to a number of unique engineering solutions, the shields are optimised to develop thin beds with capacity of 0.85 m and over as part of the longwall face systems. This year, the powered support has undergone successful tests and proved its compliance with the requirements of the European standard; it sustains over 30 thousand cycles of load, which is 13% higher than the standard.


It should be reminded that Corum Group opened its representative office in Poland in 2013 and made its first deliveries after only a year. Today, the KPD heading machines are successfully operated in such Polish mines as Jastrzębskiej Spółce Węglowej S.A. (JSW SA) and Węglowa S.A. (KW SA). The shipment of one more machine is planned for the beginning of 2016. Besides, the Group is holding negotiations with one of its current customers about its buying a second KPD machine; this delivery was earlier agreed as additional under the concluded contract.


In 2015, Corum is going to take an active part in the new circle of tenders, which the Polish mines will conduct to renew their equipment stock. Today, the KPU heading machine, which is rather promising for the Polish market, is already participating in one of the tenders.



Information about the KPD heading machine


The KPD heading machine is intended to destruct rock with hardness up to 100 MPa, to load and transport the destructed rock during roadway development with different shape and cross-section ranging from 11 to 30 m2.


The model is favourably compared with its predecessors by innovative design of the conveyor turning section reinforced with metal structured primary units, the increased resource of the reducing gear of the controlling element and a number of other improvements.


The 40 tonne KPD heading machine is equipped with an electronic visualisation system enabling to execute remote control and, if required, to plan preventive maintenance of various units. In 2014, the machine obtained an international ATEX quality certificate, which proves that it can be safely used in potentially explosive conditions. The heading machine won the Grand Prix at Ugol Rossii & Mining International Fair 2012 and is a record holder in tunnelling operations in Ukraine.


Information about the KPU heading machine


The KPU heading machine is intended to destruct rock with hardness up to 120 MPa, to remove and transport the destructed rock in the process of development of 13 to 40 square meter section temporary roadways having an arch, trapezoid and rectangular shape.


The 70 tonne KPU heading machine is a heavy category machine. It has higher productivity compared with the middle category KPD machine, and the increased capacity of controlling element engines enables it to destroy more massive rock.
