Surface Mining at its Best
01 May 2020
With the 220 SM surface miner, Wirtgen is unveiling a machine designed especially for use in small and medium-sized mining operations as well as for routing work and infrastructure projects.
Selective extraction of raw materials
With a cutting width of 2.2 m and a cutting depth of up to 300 mm, the 220 SM can extract raw materials up to a uniaxial compressive strength of 50 MPa. The extracted material is deposited behind the machine in a windrow and then loaded onto trucks with wheel loaders. Selective extraction makes it possible to mine raw materials with a high level of purity. The use of surface miners also reduces the amount of equipment, maintenance, and time required compared to drilling and blasting or rip-and-stack mining. In addition,
