"Improving Performance in Thin Seam Open Cut Mining ...

With the current challenges facing the Australian coal industry, a major Australian coal miner has achieved significant improvements from the implementation of a continuous mining system, a Wirtgen Surface Miner 4200 SM, at an open cut coal mine in South East Queensland. Due to the multiple thin seam characteristics of the deposit, selective mining practices are critical.
