The invention is directed to a method of stabilizing tailings deposits for mine tailings as well as to a method which permits re-vegetation of those tailings deposits. Mine tailings are generally finely divided, homogenous rock and other mineral particles, which are unstable due to their fineness and particle size. The invention provides a method of stabilizing the tailings deposits by interspersing throughout the tailings deposits a plurality of very large aggregate pieces which are immensely larger than the particles of the tailings. The very large aggregate pieces may very conveniently be used automotive tires. The tires are generally placed in non-uniform layers throughout the tailings deposits. It is convenient to place the tires in the tailings deposits in a pile or pond as it is being formed, but it is possible that they may be placed at least in relatively accessible portions of the tailings pile or pond after it is formed. The presence of the used automotive tires throughout the tailings deposits provides a matrix through which root systems of vegetation such as bushes, shrubs and trees may gain purchase in the tailings deposit pile, so that the tailings area may be re-vegetated by other than simply grass or weeds. Re-vegetation of a tailings area ensures even greater stability againstsslides or shifting, as well as maintaining the integrity of the tailings area against dust blowing away from it in windy conditions.
