Based on the hypothesis of comprehensive effect of gas outburst and the theory of three factors of outburst, through summarizing and analyzing the accident investigation reports of major outburst accidents in Guizhou, Yunnan, Shaanxi and other regions in recent years, it is concluded that the direct cause of outburst accidents is the lack or improper of outburst prevention measures, and the other is the most critical one Element is the change of geological structure. Based on the three factors theory of outburst, through the analysis of the traditional method, through analyzing traditional static prediction techniques such as comprehensive index method and drilling cuttings gas desorption index method for working faces, the existing traditional prediction technology index is lack of expression of geological structure, can not effectively reflect the geological situation of working face; combined with the current development status and application effect of borehole geophysical technology, in order to make up for the traditional working face The technical index of static prediction method of outburst danger is missing in the expression of geological structure. On the premise of fully discussing the importance of traditional prediction technology and the necessity and key of geological exploration for outburst prediction, the author puts forward a new idea of outburst danger prediction technology in “N + 1” working face, which provides an innovative direction for the development of outburst prediction technology in working face.
