The invention relates to an all-steel giant engineering radial tire tread rubber formula. The rubber is prepared from the following raw materials in parts by weight: 55 to 65 parts of natural rubber,20 to 25 parts of carbon black, 5 to 10 parts of white carbon black, 1 to 2 parts of a silane coupling agent, 2 to 3 parts of zinc oxide, 1 to 2 parts of stearic acid, 2 to 3 parts of an anti-aging agent, 1 to 2 parts of a softening agent, 1 to 2 parts of sulfur, 0.5 to 1 part of an accelerant and 0.2 to 0.5 part of a scorch retarder. Two-stage masterbatch and one-stage final mixing are adopted tocomplete the preparation of the tread rubber material. The prepared tread rubber is suitable for use in specific environments such as coal mines.
