World Coal Resources: Methods of Assessment and Results is an English translation of the German book Weltkohlenvorràte. This book presents detailed coal resources estimates for the world, and it illustrates and assesses the methods that are used to calculate them.
Kazakhstan contains central Asia's largest recoverable coal reserves, 3.69% of the world total. is the former Soviet Union's 2nd largest producer, after Russia. According to the Kazakh Ministry of Energy and Natural Resources, the country aims to be producing 100 – 105 million tonnes annually by 2015.

An estimate differs from an assessment, which is an analysis of all data concerning an area's coal resources and reserves with the objective of reaching a judgment about the geologic nature and economic potential of the coal resources and reserves of the area.
Proven coal reserves are defined as those coal deposits that have been confirmed by exploration, drilling and other means, and which are economically and technically extractable. It has also been estimated that the worldwide production (i.e., mining) of coal amounted to about 5.5 gigatonnes (Mt) as of 2007.
