The invention discloses mining engineering tire tread rubber and a preparation method thereof, and belongs to the technical field of mining engineering machinery tire tread rubber. The technical scheme of the invention is as follows. Comprising the following components in parts by weight: 100 parts of a rubber component, 35-55 parts of carbon black, 6-8 parts of tear-resistant resin, 10-20 parts of white carbon black, 2-4 parts of a silane coupling agent, 1-2 parts of alkylphenol tackifying resin or p-tert-octylphenol formaldehyde tackifying resin, 3-5 parts of diisopropyl boroxane polycarbonate short fibers, 3-5 parts of an anti-aging agent, 1-2 parts of microcrystalline wax, 3-5 parts of zinc oxide, 1-2 parts of stearic acid and 1.5-2.0 parts of sulfur. And 1.2 to 2.4 parts of an accelerant. The tread rubber disclosed by the invention is used for the tire of the mining engineering vehicle, has relatively low heat generation performance and relatively good wear resistance and cutting resistance, solves the problem that the heat generation performance, the wear resistance and the damage resistance of the mining engineering vehicle cannot be considered at the same time, and prolongs the service life of the tire.
