Mechel, one of Russia’s leading mining and steel companies, has launched a new longwall at the Southern Kuzbass Coal Company-owned V.I. Lenina underground mine in Russia.

Investment in the new longwall totalled around RUB470 million ($6.4 million), the company said.

The new longwall #0-16-10’s reserves are estimated at 435,000 t, with the average seam height coming in at 1.8 m. The longwall is nearly 200 m long with an extraction panel of 720 m.

The longwall is equipped with a 134-section powered support system, a cutter-loader, as well as a crusher, longwall conveyor and belt conveyor, Mechel said. All the longwall’s equipment is compliant with modern industrial and labour safety requirements, it added.

“V.I. Lenina Underground Mine’s reserves consist of coking coal with excellent quality characteristics, which is high in demand with coke producers,” Mechel Mining Management’s Chief Executive Officer, Igor Khafizov, said. “Southern Kuzbass Coal Company will be working this new longwall for eight months. The concentrate we will produce from its coal will be marketed both domestically and internationally.”

Mechel PAO says its Southern Kuzbass Coal Company unit has launched a new longwall at the Sibirginskaya underground coal mine, in Russia.

The new longwall 3-1-11 is located 450 m underground at Sibirginskaya, is 220 m long, has an average seam height of 4 m and an extraction panel of 750 m. Investment in the project totalled over 838 million rubles ($12.9 million), Mechel said.

The longwall is equipped with a cutter-loader, a belt car and crusher, drag bar conveyor, a 400- and a 1,500-m belt conveyors, and a 130-section powered support system, according to Mechel To ensure high production efficiency and labour safety, the mine also acquired a mobile vacuum air pump degasser, it said.

The longwall launch follows the startup of another new longwall at the VI Lenina underground mine in August.

“The longwall 3-1-11 with estimated coking coal reserves of 3.5 Mt is equipped with the newest mining machines acquired as part of Mechel’s investment program. Its planned monthly output is 90,000 t,” Mechel Mining Management OOO’s Chief Executive Officer, Igor Khafizov, said.

Mechel testing out polymer-coated cable ropes on Russia mining excavators

Mechel’s Beloretsk Metallurgical Plant (BMP) is conducting field tests of its new polymer-coated cable ropes at Southern Kuzbass Coal’s (SKC) coal pits and Korshunov Mining Plant’s (KMP) iron ore operations, both in Russia, the company has said.

The cable ropes have already demonstrated a good enough performance for BMP to confirm it will start producing these cables on an industrial scale early in 2019.

The ropes will replace imported counterparts in the mining and oil industries, as well as engineering, bridge- and shipbuilding, Mechel said.

When field-tested on SKC’s EGK-20 excavator, a 57 mm polymer-coated cable rope worked for over six months. It has been used since February through August in temperatures ranging from -45°C to +35°C. During this time, the excavator loaded 1.04 million cubic metres of ore, with the rope’s running time more than doubling.

SKC, a subsidiary of Mechel, is still testing a 52 mm cable rope, which was installed at an EKG-12 coal-loading excavator in early July. The rope has already worked for 55 days, with an average service life of 60 days typical for uncoated ropes on this type of excavator.

“The polymer coating is still in good shape and the rope is still being used,” Mechel said.

Meanwhile, 45.5 mm cable ropes are being tested at KMP’s iron ore mines. These were installed on an EKG-8I excavator’s hoisting, thrust and recoil gear in February.

“The ropes have already worked for 183 days, running an accumulated 477,000 cu.m. This is 67% more than the running time for uncoated hoisting cables, 95% more than uncoated recoil cables and more than double…uncoated thrust cables,” Mechel said.

BMP CEO Viktor Kamelin said: “The results we received lay the groundwork for our presentation we show to both Russian mining facilities and those in the neighbouring countries. Our new products have excited interest and we already have preliminary agreements on delivery of test batches.”

The plant has been implementing a project to replace imported multi-strand cable ropes since 2015 with the support of Russia’s Industrial Development Fund and the Republic of Bashkortostan’s government.

BMP plans to produce six to 12-strand cable ropes up to 90 mm in diameter, including those with a polymer coating.
