Application of join algorithm in coal mine safety production

HUANG Weili;LIU Ying;College of Information and Electrical Engineering,Hebei University of Engineering;  
The paper analyzed influence factors of coal mine safety production,and introduced large data technology to analyze data of coal mine safety production.It also put forward a star join algorithm based on Bloom filter to deal with the problems of multi-table connection in process of large data analysis.The experimental results show that the algorithm can improve efficiency of using large data to analyze coal mine safety production data in space and time compared with the traditional algorithm.
