Coal prices and outlook US Energy Information
Coking coal must be low in sulfur and requires more thorough cleaning than coal used in power plants, which makes the coal more expensive In 2019, the average delivered price of coking coal to coke producers was about $146 per short ton—almost four times higher than the average price of coal delivered to the electric power sector a Rand per ton of coal mined value) in an attempt to identify the most cost effective mining method from conventional drill and blast, mechanized continuous mining, and mechanized longwalling His analyses were based on the following assumptions: Seam height = 3 m Competent sandstone floor Coal roof Depth below surface = 90 mActivity Based Costing: Challenging the way we cost In its “Coal Information” report for 2012, the IEA said that between 2008 and 2010 it required $780 a ton for new production capacity and that those costs would rise to $930 a ton Cost of mining coal continues to climb The Washington Post
