In order to use the non-touch electromagnetic emission (EME) method to better forecast or predict the danger of coal or rock dynamic disaster such as coal or gas outburst, rock or coal outburst and so on, the direction and location of dangerous areas, that is, how to ascertain the monitoring direction and position for EME, is studied. The research results show that according to the computation for the changing rules of EME signals in various directions by means of the coupling equation between EME and stress, and the EME numerical results comparisons for the designated monitored spot, the best monitoring direction and the direction with most stress or maximum dangers can be ascertained. When dynamically monitoring the EME signals in tunnel head-on in the course of tunnel excavation, the monitoring antenna should be laid at the middle height of tunnel and faced with the coal stratum direction. The outburst danger can be monitored by altering the antenna monitoring direction. The available scope of prediction distance can be determined in light of the stress concentration ascertained by numerical simulation for stress field. The EME measuring results on the spot show that it is feasible to study the direction and location of dangerous areas in predicting the danger of coal or rock dynamic disaster by means of the coupling between EME and stress.
