A Wirtgen surface miner is a crawler-mounted mining machine with a rotating cutting drum for rock penetration mounted at the center of gravity (Fig. 1). This ensures that the full machine weight of the miner can be transformed into rock …

Almost 8000 t of material was screened to compare the material produced by Wirtgen surface miners and conventional mining methods. In one coal mine, Wirtgen surface miners are operating alongside dozers that employ the conventional rip-and-stack method. In view of the current coal prices, the mine was optimizing every step of the operation.

In addition to the 2500 SM surface miner that the company has used in Ube since 2012, in 2018 the service provider decided to add a second miner – the Wirtgen 2500 SM Vario. The surface miners allow Okumura to create extremely stable and steep mining walls with narrow benches for Ube Industries, thus safely expanding the mining area.
