  • Change Your MineHow Continuous Surface Mining Works

    Safety challenges Helps eliminate many of the safety challenges and restrictions associated with drill and blast. Fewer underground concerns Eliminates seismic waves so operators can mine closer to underground pipelines areas with high water tables or underground utilities. Continuous surface mining Allows operators to follow the seam for less contamination and selective loading methods.

  • Methods and costs of thin-seam mining. Final report 25

    The results are a compendium of thin seam removal methods and costs. The work explains how the mining industry recovers thin coal seams in western surface mines where extremely thick seams naturally hold the most attention. It explains what new developments imply and where to look for new improvements and their probable adaptability.
