Abstract Geological structure in North China Coalfield is complex,with incomplete coal floor. Portions of coal seam water inrush coefficient over 0.06 MPa/m, it belongs to potential water hazard areas, this part of the coal seam can directly affects the safe mining of the mine production links and future development of the mine. So a set of three-dimensional integrated water control technology was put forward, this technology was successfully applied in FengFeng Mine, with important reference value and guiding significance for mines under similar condition.
