The invention belongs to the technical field of clean coal production, and specifically relates to a clean coal and a production method thereof. The clean coal is composed of the following raw materials in percentage by weight: 10 to 20% of anthracite slime, 60 to 80% of smokeless coal, 10 to 20% of semi-coke, and 2 to 3% of adhesive. The clean coal comprises the following components in percentage by weight: 13 to 18% of water, 18 to 23% of ash, 7 to 12% of volatile compounds, and 0.1 to 0.4% of sulfur. The calorific value is 5800 to 6000 KJ. The preparation method of the clean coal comprises steps of blending coals, grinding, blending, stirring and wetting coals, pressing coals into balls, drying, packaging, and taking out finished products from a warehouse. The clean coal has the advantages that the clean coal is convenient for storage and transportation, does generate pollution and smoke during the burning process, is odorless and dust-free, and is low in sulfur; moreover, the burning time is long, the calorific value is high, the burning is complete, the ash content is low, the burning state is stable, the harm to the environment is little, and the shape and size are standard.
