Steep seam coal mining in Western Canada by open pit mining

, 1984
Canada produces close to 42 million tonnes of coal per annum of which soma 38 million tonnes is produced by surface mining methods. The two Western Canadian provinces, Alberta and British Columbia, produce 31 million tonnes of coal by surface mining. These two provinces provide the bulk of the metallurgical coal for export. The geological conditions in
