What does this data set describe?

Title:
Coal-Bearing Regions and Structural Sedimentary Basins of China and Adjacent Seas: Major coal mine locations
Abstract:
This dataset is a collection of major coal mine production located in The Peoples Republic of China. Included in this dataset are the locations of major coal mines and the approximate annual amount of coal mined annually in millions of metric tons.
Supplemental_Information:
Procedures_Used: The major coal mine production points were digitized from the Coalfield Prediction Map of China, utilizing ARC/INFO. Revisions: none Reviews_Applied_to_Data: None
