Starting in 2017, the Ministry of Ecology and Environment began to implement a pollution permit system nationwide, in which environmental protection authorities issue permits to enterprises and institutions and supervise them in accordance with the permits. The accounting results of pollutant emissions are an important basis for the issuance of emission permits. At present, the air pollutant accounting methods for emissions from fixed emission facilities are mature and reliable, while there is no mature calculation method for coal dust emission in open storage yard. In this paper, based on the data of area, volume and coal nature of open storage yard in the coal port area of Huanghua Port, the author calculated the strong dust source under different wind speed by using the calculation formula of bulk dust amount in large ports, so as to provide technical support for the forecast study of atmospheric environmental impact in the coal port area of Huanghua Port and the calculation of total atmospheric particulate emission by the environmental management department.
