Although I understand the message you're trying to portray across, BUT... that's not the coal we're mining. We're mining High carbon content coal, also known as 'Coking Coal', used for the production of steel in industry.. an important requirement for all growing industrial economics!
....And to put icing on the cake, it's much more expensive than standard 'thermal coal', (article), by the ton!
