The invention relates to a process method for improving blast-furnace iron-making output and lowering blast-furnace coke ratio. In the method, the blast-furnace output is improved and the blast-furnace coke ratio is lowered by increasing the qualification rate of a Tfe blending material pile; and the demand quantity for increasing the qualification rate of the Tfe blending material pile is obtained by lowering the fluctuation section of the Tfe blending material pile. The method is specific and operable and catches essence through phenomena as compared with the experimental data in the prior art. In the specified production assessment criteria, as long as the qualification rate of the Tfe blending material pile is improved, the anticipated increment of the blast-furnace iron-making outputand the reduction of the blast-furnace iron-making coke ratio can be obtained.
