The invention provides a coal conveying method. The method comprises the following steps that a coal feeder is started to supply coal to a coal bin, and the coal entering the coal bin is weighed through a furnace-entering belt weigher; the height of the coal in the coal bin is detected periodically by a detector; when the detected height of the coal is in a preset height value range, the coal feeder is controlled to supply coal to the coal bin normally; and when the detector detects that the height of the coal in the coal bin exceeds the greatest value of a preset height value, the coal feederis controlled to stop supplying coal for a preset time until the height of the coal in the coal bin is in a preset height value range. By adopting the coal conveying method, the coal conveying difficulty can be effectively lowered; the accuracy detection efficiency of the furnace-entering belt weigher is improved; labor and material loss is greatly reduced; and besides, on-line comparison is performed on the furnace-entering belt weigher on the condition that coal feeding is not affected, so that the monitoring strength of the accuracy of the furnace-entering belt weigher is improved.
