GROUTING BY CONTROLLED GYPSUM CRYSTALLIZATION FROM SUPERSATURATED SOLUTIONS-A NEW WAY TO REDUCE BRINE INFLOWS INTO SALT AND POTASH MINES

摘要：

1. IntroductionThe Mosaic K2 Esterhazy potash mine has been successfully controlling an inflow of brine since 1985. Inflow rates have averaged about 3,500 gallons per minute (gpm), or nearly 0.2 cubic meter per second (m3/s). The inflows originate from the fractured Dawson Bay formation overlying the mine. The Dawson Bay formation consists of dolomite, limestone and minor beds of anhydrite and mudstone. The inflows are typical sodium chloride (NaCl) brines with-sulfate concentrations of 0.2 to 0.3 wt.-％.
