    • Abstract
  • Coal crack and destabilization quantitative experiment is a fundamental study on forecast dynamic hazard of gob area.Based on similarity material simulation experiment during coal crack and dynamic destabilization of gob area,forecasted different phases during coal crack by SVM technique,found out alarm value for stress-displacement-acoustic emission during coal medium crack and sudden destabilization of large scale gob area.By applied quantitative criteria for danger source discrimination and alarm induced dynamic hazard during mining,predicted rule timely and accurately for coal crack and destabilization of gob area.It provided for efficient guidance of the mining.
