The invention discloses a comprehensive cooling and directional static blasting device which includes a blasting tube plugged into a drilled blast hole. The central axis of the blasting tube is provided with a cooling steel pipe in a penetrating manner, flowing water is guided into the cooling steel pipe, and the water quantity is controlled by a water conveying device; the blasting tube and the cooling steel pipe are connected through a connecting rod, the outer side of the blasting tube has a triangular prism blasting angle; the direction of the blasting angle is adjusted according to the pre-splitting direction so that the blasting angle can coincide with a pre-splitting line; a static blasting agent is injected into the position between the blasting tube and the cooling steel pipe, andthen water is added to generate a hydration reaction to generate crystals; and the water passes through the cooling steel pipe through the water conveying device, the water flow is adjusted to control the reaction temperature, the optimal reaction temperature is reached, and waiting for completion of blasting is realized. By means of the comprehensive cooling and directional static blasting device, the mechanics principle is used for applying force of an expansion agent to a line, the blasting effect is improved, and the blasting direction can also be controlled. A water supply reaction is used for cooling to eliminate the spray hole phenomenon, recycling of cooling water during blasting can also effectively reduce noise, and explosives are saved.
