Coal is an underground resource (anybody had any doubt ?). The Devil can be in details here also, because when going from one unit to the other the result can be multiplied by 2 for a same country !
The good question is: by how much ? The graph below nevertheless gives an idea of the figures we are talking about. As for all resources that are mined (including gas and oil), when it comes to discussing figures we will use in turn three different notions: As for oil and gas, the proven reserves, that correspond to the first definition, is the only amount for which figures are widely published (or at least are published, even if it is not widely !). Indeed, extracting oil is forcing the circulation of a very viscous fluid through the very small pores of a rock, first through benefiting of the initial pressure of the reservoir, and then through creating this pressure from the surface. (see below).
As well, this number doesn't take into account of discoveries of new reserves or developments that allow fuel to be extracted from current resources.[2]. If this price increases, it does allow to use more sophisticated – thus more expensive – enhanced recovery techniques and to access more complicated fields, but it does not multiply recoverable oil by 3 (and most of all does not multiply by 3 the possible production, but rather prolongates a given level of production). Somebody used to oil or gas will probably answer: they do nothing else than increasing ! No more than for oil or gas the coal producer guarantees that the production coming from his reserves will be forever increasing or even constant. In addition to the knowledge of their existence, these reserves are also accessible and coal can be produced from them economically. The relative merits of standard washability curves and other graphical methods of representing coal cleaning potentials are discussed with particular … »More detailed No more than for oil or gas these proven reserves can include coal whose existence is absolutely certain but which is not located in an active mine (or sometimes a mine under development). The situation is definitely more favourable to Occidental countries than for oil, but still 8 countries own more than 90% of the world proven reserves (and the first four own two thirds of the total). So there is coal and coal, in spite of the same word being used for all possible types of solid fossil fuels.
This resource are is determined from the thickness projection and covering soil, layers and quality of data from the measuring point and sampling based on the geological evidence in the radius of 0.4 km. [1] Most of the worlds coal is buried deep underground and is extracted with traditional mining methods. The same BGR publishes otherwise estimates of coal in place that are consistent with the above figures (remember that a division by 3 to 4 is done when going from coal in place to ultimate reserves), with a breakdown by country. The largest owner of fossil carbon is… American ! World Coal Resources and Reserves.
