Abstract: Based on the construction of intelligent mine in coal mine and massive data of monitoring system networking platform, valuable data are extracted from the existing massive data and its internal relevance is analyzed by studying key core technologies such as Hadoop and Hive, data warehouse technologies such as data cleaning and data conversion, and big data means such as mathematical analysis model abstraction and mining. Extract valuable data from existing massive data, analyze its internal relevance, identify and analyze abnormal data, find out the potential risk points of illegal operation in coal mines, and help coal mining enterprises to eliminate safety risks in time.
