The Quảng Ninh Coal Basin has been studied in several phases: word mapping, preliminary search, and exploration. However, coal resources below the depth of -500 m have not been evaluated. The geological structure of the mines is quite clear, but the geological structure of the coal reservoir still is not clearly showed. The quantity of coal resources is forecasted with various data. Coal resources have not been updated. This state badly influences on the planning of coal exploration and exploitation. Therefore, it is required to perform some necessary geological tasks with the Quảng Ninh coal basin in the near future.
