The invention provides a coking technology for briquettes containing low-rank coal, garbage and biomass. The technology comprises loading low-rank coal and garbage into a bundle-shaped material formed through packing of biomass, and then performing compacting treatment on the obtained material with a core-shell structure under specific conditions, so as to prepare the briquettes containing the low-rank coal, the garbage and the biomass. Therefore, the low-rank coal, garbage and biomass raw materials can be pushed into a stamp-charging coke oven for high-temperature dry distillation, and also, solid products generated after dry distillation of the low-rank coal, the garbage and the biomass can be easily pushed in the stamp-charging coke oven, and thus a considerable amount of raw gas, tar and carbon residues can be obtained. The technology of the invention not only can reduce the raw material cost of oil gas and coke products, but also can effectively realize resourceful utilization of garbage and biomass, and accordingly has both considerable economic benefits and certain social benefits.
