Analysis on Theoretical Defects of Water Inrush Coefficient in Coal Mining under Safe Water Pressure

Abstract:

Based on the analysis and research on the improvement of water inrush coefficient in deep coal mining under safe water pressure, the author pointed out that water inrush coefficient exits some major theoretical defects in calculation and application at present. The paper stated the choice of equations, choosing parameters and some issues in water inrush coefficient. It was pointed out that critical values are the key for the new equation of water inrush coefficient to be popularized and applied.
