The invention relates to the technical field of open pit coal mine blasting dust fall, in particular to an open pit coal mine blasting dust fall system and method.The method comprises the steps that a dust diffusion image set of blasting is recognized through a dust shape recognition model, and the dust diffusion volume is obtained; the dust concentration is obtained through an optical dust detection instrument, and the dust prediction amount is obtained; weighting the dust fall water demand threshold value by combining the dust particle size, the humidity coefficient, the wind speed coefficient and the temperature coefficient according to the ratio of the dust predicted amount to the dust amount threshold value to obtain the dust fall water demand; the dust falling position of the unmanned aerial vehicle is determined through weather data, the dust concentration under the dust falling unmanned aerial vehicle is detected, and the spraying speed of the dust falling unmanned aerial vehicle is calculated by combining a dust concentration threshold value and a spraying speed threshold value. The dust prediction amount is obtained through image recognition prediction, the threshold value is set in combination with data obtained through the blasting experiment, the water demand and the spraying speed of dust falling are calculated, and guidance is provided for accurate and efficient dust falling of the open pit coal mine.
