The Wuda coal mining area in Inner Mongolia Autonomous Region, China, is one of the largest coal fire areas world-wide. At the same time it is also one of the most extensively researched ones.
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, or strip) mining methods. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. Large Open Cast mines can cover an area of many .

paper. The future research focuses regarding water-preserved coal mining in China are also discussed in this paper. Its results serve as a guide for selecting the methods to be preferred for mining in case the geological conditions, roof overburden structure and coal mining process are similar to Yushenfu mining area.
So the idea of mining and finishing whatever stocks of coal remain before such a replacement happens weighs heavily on the minds of policy makers. Hence the near-frenetic activity in coal mining in places like India and China. Also, both depend heavily on this mineral to make-up for the huge shortfall in oil to meet their ever-growing energy needs.
