Abstract: In the process of coal mining in our country,we can’t really use the data to make a good use of the data,and also can not to provide reliable data support for coal mining,and research and analysis of the application of big data technology in the coal production industry.This paper first introduces the basic concept and characteristics of intelligent mine and its value expression,summarizes the research and application status of intelligent mine big data at home and abroad,and analyzes the driving factors and existing obstacles of the development of smart mine big data technology.By analyzing the data source,data integration and data analysis application in the intelligent mine,the key technologies of big data in the intelligent mine are summarized，such as data acquisition technology,data integration and fusion technology,big data analysis and mining,analysis and application technology of big data.By analyzing the big data platform architecture,the physical architecture of big data platform and the application cases in the overall architecture construction of Shendong Intelligent Mine,the paper provides the large data of intelligent mines should be applied and researched in the fields of mine safety management,production execution,management and so on.At last,some suggestions on the construction of intelligent mine in China are given.
