Abstract:
The accuracy and timeliness of the rock burst monitoring and early warning cannot meet the needs of the field engineering. According to the theoretical research, software development and field practice, a rapid decision method which is based on the contours of vibration and stress fields is proposed to identify the rock burst hazard zones. The vibration contour can be used to identify the regional rock burst hazard rapidly and intuitively; while the stress contour can make early rock burst warning on partial spots. With the joint determination of the double-cloud map, it can quickly determine the rock burst danger area, and then guide the project site to carry out targeted pressure relief and support measures, thus improving the efficiency of preventing and controlling the rock burst. The results of the study have been applied in Yima Mine of Henan Province, and the effect is good.
