The invention provides a method for judging the state of a dead stock column by using the descending speed of furnace burden. The method comprises the following steps: acquiring a middle flame area of each batch after material distribution; obtaining the discharging speed of each batch; obtaining the discharging speed, detected by radar equipment, of each data point covered by the flame area; calculating an average value, a maximum speed value and a minimum speed value of discharging speeds corresponding to all data points covered by the flame area in each batch and a difference value between the maximum speed and the minimum speed; solving the average value of the average discharging speeds of all batches; obtaining the maximum value in the maximum discharging speeds of all batches; obtaining the minimum value in the minimum discharging speeds of all batches; obtaining the maximum value in the discharging speed difference values of all batches to serve as the maximum difference value; calculating the maximum
