    • Abstract
  • Seam mining easily leads large area water inrush disaster at working face,and grouting technology is an effective governance measure. Aiming at treatment problems of the Jurassic quifer roof water inrush disaster during mining in Wanglou Coal Mine,we analyze underground watercourse and concentrate inrush points according to tectonic dynamics,blocking underground watercourse by using directional drilling and contour controlled grouting technology.Combining the analysis results on inflow of water monitoring at face, hydrological changes of hydrological observation wells and geophysical prospection,the effect of grouting and plugging water is remarkable.
