The risk of water inrush from pressure mining is related to various factors. The safe head value method, the thickness of the aquifer and the water inrush coefficient method and the related inverse derivation formula derived from the Slesalev formula were used. Comprehensive evaluation of the risk of water inrush from the mining of the underground ash water in the deep coal seam of Linxi Mine, a regional water inrush prediction map was drawn, the mining location of coal ash and water in the lower part of the whole area was analyzed and predicted, giving specific prevention and control of ash water inrush, providing reference for the relevant mining engineering arrangements.
