Abstract：During a mine roadway heading in a Mine Ventilation Shaft of Mabianshan Iron Mine ,a mine strong water inrush was occurred in the heading face with a water inrush volume about 800m3/h.Thus the mine was flooded ,a control plan of a first water drainage and then water sealing was applied and the water drainage target was hard to be reached.After the expert argumentation conducted ,a control plan of a first water sealing and then water drainage was determined and applied.During the construc-tion ,two boreholes were drilled from the surface ground to the mine roadway in the underground mine and were applied individually to build a water retaining wall and to make the grouting ,backfill and sealing operations.After the construction ,the water retaining wall formed could have good pressure resistances ,the grout could have good backfill and sealing to the water flow channel with the predicted effect.In June ,2013 ,the inrush water in the mine was successfully drained off and the mine was suc-cessfully restored in production.
