Minova Australia was contacted in the very early stages as part of a rescue operation at Beaconsfield Mine in Tasmania to free two miners trapped underground following an earthquake. While initial discussions pointed towards providing either a cementitious grout or chemical foam (Bevedan/Bevedol, Wilkit or Carbofill), extensive discussions led to the request for Minova to manufacture a modified FB200 cementitious grout which would provide very specific characteristics. This included being able to flow into mullock (loose backfill material), stop the water flow into the cavity and achieve a predetermined strength within a very specific timeframe.
