The invention relates to a method for coal coking and blending based on organic sulfur-enriched high sulfur coke and fat coal. The method comprises the following steps: replacing 5 to 15% of low-sulfur fat coal and/or low-sulfur coke coal in low-sulfur coking coal with organic sulfur-enriched high-sulfur fat coal or high-sulfur coke coal to obtain primary modified blend coal; then blending 20 to 40% of high-volatile-component low-sulfur non-coking coal to obtain secondary modified blend coal; and finally blending 1 to 8% of adhesive to obtain modified blend coal for coking. The modified blend coal obtained by the method disclosed by the invention can be coked according to a normal coking step. According to the method for coal coking and blending, high-quality coking coal resources can be saved, poor-quality high-sulfur coking coal is reasonably utilized, the resource range of coking coal is expanded, and the coal blending cost is reduced.
