Mining soft rock at maximum production rates and economic efficiency – the 2200 SM 3.8 surface miner has been developed to meet exactly these criteria for success. The centrepiece of the compact, yet powerful machine is the 3.8 m wide cutting drum which offers numerous innovative features. It cuts soft rock with unconfined compressive strengths of up to 35 MPa, such as coal or salt, in a highly productive process, depositing it in three windrows behind the machine.
