Application of vibration wave CT technology in the dynamic prediction of shock hazards

The vibration wave CT detection technology could be used for forecasting dynamic disasters such as coal and gas outburst rock burst in mines well monitoring warning of impact risks. Based on the positive correlation between stress velocity abnormal distribution velocity, danger area determined. Two evaluation indexes risk were constructed: anomalous coefficient A n value m gradient variation ( VG ) velocity. critical values two corresponding to degree given. In addition, field engineering practice was carried out by using inversion results technology. Combined with geological conditions, F 15 -24080 working face defined comprehensively. showed high precision this Vibration make prediction a site provide guidance test formulation implementation effect pressure relief measures high-impact areas.
