Summary:The invention discloses a coal mine blasting longitudinal wave velocity measurement method and device, and the method comprises the steps: obtaining the first arrival time of a blasting wave reaching a source detector and the second arrival time of the blasting wave reaching a plurality of target detectors after a preset blasting object in a coal mine tunnel is blasted; respectively calculating the distance between each target detector and the source detector to obtain a source detection distance corresponding to each target detector, and calculating blasting wave travel time corresponding to each target detector according to the first arrival time and the second arrival time; calculating an initial longitudinal wave velocity corresponding to each target detector according to the blasting wave travel time and the source detection distance corresponding to each target detector, and constructing an initial longitudinal wave velocity sample set containing the initial longitudinal wave velocity corresponding to e
