STUDY ON THE PREDICTION MODEL OF SAFETY MINING UNDER PRESSURE AND ITS APPLICATION METHOD

    Graphical Abstract
    • Abstract
  • Through the analysis of practical data,the main factors influenced on the water gushing of seam floor are studied.Based on the parameters obtained from the tests,the evaluation criteria and prediction model of mining under water pressure in North China are established,and the application method is illustrated with examples.Finally,the overall division of typical mining district with large water yield in North China is given,and the corresponding control measures are presented.
