The invention discloses a bell-less material distributing method capable of ensuring stable running of a blast furnace. The material distributing method can protect a middle thin belt of a coke layer to prevent part of a coke window from being too narrow to effectively solve the problems of blast furnace gas turbulence and un-smooth charging falling, caused by over-narrow part of the coke window, thereby ensuring stable running of the blast furnace. According to the method, charging can fall stably, and the airflow distribution can be stable, so that the blast furnace can run stably for a long time, and ironmaking cost can be reduced.
