2 天前 US coal prices have jumped to their highest level since 2009 as miners attempt to keep pace with the surging demand for the fossil fuel. Demand for coal usually rises significantly during the winter months. With most coal sold under long-term contracts, the sudden rush for the remaining supplies can prompt these sharp rises.
