Research on Direction and Location for Danger Prediction of Coal or Rock Dynamic Disaster

Xiao Hohgfei,He Xueqiu,Feng Tao,Wang Enyuan

Strategic Study of CAE 2005, Volume 7, Issue 11, Pages 81-86

Abstract: use the non-touch electromagnetic emission (EME) method to better forecast or predict the danger of coalor rock dynamic disaster such as coal or gas outburst, rock or coal outburst and so on, the directionexcavation, the monitoring antenna should be laid at the middle height of tunnel and faced with the coalthat it is feasible to study the direction and location of dangerous areas in predicting the danger of coalor rock dynamic disaster by means of the coupling between EME and stress.

Keywords： rock or coal dynamic disaster danger prediction direction and location deformation and fracture of coalor rock couples between EME and stress electromagnetic emission (EME)
