The largest Russian coal producer, Siberian Coal Energy Company (SUEK), recently placed an order with the regional Cat® dealer, Vostochnaya Technica LLC (VT), for a complete armored face conveyor system to equip the company’s second 400 m longwall face.

The longwall will operate in the mine named after V.D. Yalevskyi, Yalevskogo Seam #52 (formerly Mine #7), with commissioning planned for early next year.

In April, SUEK commissioned the first 400 m (1300 ft) longwall face in Russia in the same mine, but in Seam #50, formerly called Kotinskaya. Previously, the widest longwall face in Russia was 300 m (980 ft). The equipment for the face extension and the upgrade of the armored face conveyor (AFC) system was manufactured by Caterpillar and assembled and commissioned by VT.

The mine is located in the Kemerovo District in Siberia where SUEK operates ten longwall faces in their underground coal mines and two open pit coal mines. The longwall systems at the two faces average cutting heights of approximately 4 m (13 ft).

The new system for Yalevskogo consists of a Cat AFC PF6/1142 with three drives of 1000 kW (1341 hp) each and Cat CST65 gear boxes, a Cat PF6/1342 beam stage loader with a Cat SK11/14 crusher and a belt return unit. The AFC system will go into operation with Cat roof supports.
