Method for diagnosing physical properties of coal as fired and coal charging car

The invention belongs to the field of coking, and particularly relates to a coal as fired physical property diagnosis method and a coal charging car. According to the technical scheme, the method comprises the following steps: acquiring a first bulk density parameter of coal as fired in a car hopper of a coal charging car moving back and forth between a coal storage tower and a coke oven; and obtaining a second bulk density parameter of the coal as fired in the coal storage tower. According to the first bulk density parameter and the second bulk density parameter, judging whether the mass of the coal as fired in the coal charging car accords with a controlled quantity, and if so, adding the coal as fired in the coal charging car into the coke oven; and if not, reducing/increasing the addition amount of the coal as fired in the coal charging car to the coke oven according to the first bulk density parameter. The carbonization chambers can be correspondingly controlled according to the physical ...
