The invention belongs to the technical field of industrial production, in particular to a high-precision prediction method for a feeding speed of a blast furnace. Aiming at the problem of equipment capacity waste caused by the influence of a furnace top feeding mode on the feeding speed, the high-precision prediction method comprises the steps of: establishing a mathematical model for a blast furnace feeding system, converting a material-needing quantity model into a time length model, and providing a high-precision algorithm for predicting a blast furnace feeding speed. According to the high-precision prediction method, the composition logic of a material-needing signal is divided into a batch-based material-needing mode and a tank-based material-needing mode, the material-needing modes and feeding speeds are analyzed respectively in a mode when furnace condition of the blast furnace is good and the equipment operates stably as well as in a mode when furnace condition of the blast furnace is not favorable an
