Mechel PAO, a Russian mining and metals company, has reported the launching of a new longwall at Sibirginskaya Underground Mine, which is part of Southern Kuzbass Coal Company.
The new longwall 3-1-11 lies 450 m deep and is 220 m long, with an average seam height of four meters and an extraction panel of 750 m.
Investment in the project totalled over RUB838 million.
The longwall is equipped with a cutter-loader, a belt car and a crusher, drag bar conveyor, a 400 and a 1500 m belt conveyors, and a 130 section powered support system. To ensure high production efficiency and labour safety, the mine also acquired a mobile vacuum air pump degasser.
“The longwall 3-1-11 with estimated coking coal reserves of 3.5 million t is equipped with the newest mining machines acquired as part of Mechel’s investment programme. Its planned monthly output is 90 000 t,” Mechel Mining Management OOO’s CEO Igor Khafizov noted.
