The invention relates to the field of solid waste resource utilization and discloses a stripping rock tailing dry-method desliming method. The technical problems that in the prior art, during stripping rock tailing desliming, water consumption is high, the cost is high and time is wasted are solved. The method comprises the steps that the total mass of slime in an excavation tailing area is estimated; a desliming agent is added into the excavation tailing area; the excavated tailing and the desliming agent are mixed and piled; a preset amount of water is sprayed to the piled mixture so as to wet the mixture, and the preset amount is 10-15% the total mass of the slime of the excavation tailing area; the mixture with the sprayed water is placed for 2-6 h so that the desliming agent can react with soil particles in tailings; the placed mixture is contained in a breaker for breaking; the broken mixture is sieved, wherein the part, with the diameter not larger than the preset diameter is adopted as tailing slime t
