In view of problems of great limitation in actual application and bad precision of prediction result of current gas outburst prediction method,the paper proposed a gas outburst prediction method based on ACA-FAM algorithm.It analyzed basic principle and implementation steps of ACA-FAM algorithm.Taking data of gas outburst of underground working face of a Coal Mine in a certain period as example,it used ACA-FAM algorithm to make mining analysis for the data to find relations between gas outburst and influenc...
