The invention discloses a super-thick bed layer sintering production method. The super-thick bed layer sintering production method is characterized in that during sintering production, material distribution is performed twice, ignition is performed twice, and carbon-containing pellets are added after first material distribution and before first ignition as well as after second material distribution and before second ignition; the thickness of the mixture distributed for the first time is 600-800 mm, the carbon-containing pellets are added into the mixture distributed onto a sintering machine for the first time, the quantity of the carbon-containing pellets added around the mixture is 1-2 times of that of the carbon-containing pellets added into the middle of the mixture, and ignition and down draft sintering are performed; second material distribution is performed after the sintering lasts for 10-25 minutes, the material distribution thickness is 400-600 mm, the carbon-containing pellets are added into the sintering mixture distributed for the second time, the quantity of the carbon-containing pellets added around the mixture is 1-2.5 times of that of the carbon-containing pellets added into the middle of the mixture, and the second ignition and down draft sintering are performed. The super-thick bed layer sintering production method has the advantages that the upper mixture and the lower mixture are sintered at the same time, and the bed layer thickness can be increased to 1.3-1.4 m; the heat supply and mineralization time of the upper and peripheral bed layers are optimized, sinter quality can be improved, and solid fuel consumption is lowered.
