Russian coal company, SUEK, has ordered a new Cat® armoured face conveyor and beam stage loader for its Kotinskaya coal mine in the Kuzbass region of Russia. The Kotinskaya mine holds the Russian longwall production record using its existing Caterpillar longwall equipment.

The Caterpillar Global Mining facilities in Lünen, Germany ,will manufacture the high capacity system, while Vostochnaya Technika UK, the Caterpillar dealer in the region, will deliver and support it. Delivery is scheduled for March 2016.

The new hardware includes a PF6/1142 AFC with a length of 306 m (1000 ft). Three Cat CST gearboxes will be powered by three motors of 750 kW (1000 hp.) each. The Cat stage loader type is PF6/1342 with a conveyor length of 29 m, powered by a 200/400 kW (265/535 hp.) drive system. Crusher motor power is 400 kW (535 hp.). A belt return unit is also part of the package.

Kotinskaya’s current longwall is equipped with two-leg Cat shields, each with a width of 1.75 m (5.75 fe) and support capacity of 725 t (800 short t). With an operating range of 2.2 to 4.8 m (7.2 to 15.7 ft), the supports are used in a seam that is typically slightly more than 4 m thick. The mine currently produces about 3 million tpa (3.3 million short tpa) of coal.
