Anchor themes. Our global mining team projects large supply deficits in the global seaborne thermal coal market over the next five years, with import growth (driven by India and China) outstripping export growth (driven by Australia and Indonesia). Strong domestic demand is likely to offer another boost to the sector.

Cardinal River Coal Mining in Westcentral Alberta. An open pit mine is a devastated landscape; trees, soil and overburden are removed to retrieve coal that may be up to 215 m underground. Overburden and soil are returned, but the disturbance compares to the barren landscape left behind by glaciers.

In the working areas, the coal was loaded into mine cars and pulled by mules to the tipple or to the bottom of the shaft or incline for hoisting. Underground, the dip of the coal beds dictated the mining method to be used. In generally flatlying beds, variations of room and pillar mining were used.
