[0002] The field mixed emulsion explosive is a key development direction of the civilian explosive industry, and has been widely and well applied in open-pit mining. However, in the upward hole blasting construction in the underground, in order to meet the pumping conditions, the field mixed emulsion explosive needs to have a certain fluidity. Since the better the fluidity of the field mixed emulsion explosive is, the shorter the time required for sliding a certain distance is, the more likely the return medicine phenomenon is, the worse the anti-return medicine performance is, and the greater the angle between the blast hole and the horizontal direction is, the more likely the return medicine phenomenon is. Generally, the fluidity of the field mixed emulsion explosive is greatly affected by the temperature. The higher the temperature is, the better the fluidity is, and the more serious the return medicine phenomenon is.
