A study was conducted to assess the feaeibility of increasing the heap height above one lift at the Alligator Ridge Mine. This study concentrated on the physical aspects of the heap and liner performance. Two principle aspects were addressed during this investigation: (a) the adequacy of heap permeability under present and future loading conditions; and (b) the adequacy of the liner to limit seepage losses. Field and laboratory test a were performed and their details and results are presented. It was concluded that the permeability of the heap would remain adequate for higher heap. The geometry of the heap will be the major constraint. It was also concluded that the liner would perform satisfactorily beneath higher heap.
