The invention relates to a method for increasing the yield of super-thick material layer sintering. Hot pressing pellets with the alkalinity being the same as that of a sintering mixture are distributed into the sintering mixture, so that ventilation holes are formed in an upper sintering material layer during ignition sintering. The method comprises the steps that 55-70 wt% of iron concentrate and 30-45 wt% of soft coal are fully uniformly mixed, then quick lime is added into the iron concentrate and the soft coal to form a mixture, the binary alkalinity of the mixture is made to be the same as the alkalinity of the sintering mixture, the ratio of CaO to SiO2 is 1.8-2.4, 2-5 wt% of water is added into the mixture, and the mixture is fully stirred and uniformly mixed in a mixer; a uniformly mixed mixture is subjected to hot pressing forming through a ball press machine, wherein the forming pressure is 20-30 MPa, the hot pressing temperature is 350-550 DEG C, the hot pressing time is 8-15 min, and the diameters of obtained hot pressing pellets are 8-12 mm; and the hot pressing pellets are distributed into the sintering mixture layer through a distribution device arranged between a sintering distributor and an ignitor, wherein the amount of the hot pressing pellets distributed into the edge sintering mixture is 1-2.5 times that of the hot pressing pellets distributed into the middle sintering mixture, and the depth of the hot pressing pellets distributed into the sintering material layer is 20-200 mm.
