The invention relates to a carbon dioxide phase change coal seam fracturing device and a utilization method. A barrel is in threaded connection with a valve. The carbon dioxide phase change coal seam fracturing device is characterized in that the two ends of the barrel are in threaded connection with connectors with explosion venting holes, the connectors are provided with cable passing holes, and cable grooves for containing a cable are formed in one sides of the barrel and the two connectors. Due to the fact that the cable is placed in the cable grooves, or one pole of the cable is placed in the barrel, and the barrel is placed on the other pole of the cable, or the whole cable is placed in the barrel, and meanwhile the utilization method is provided, when conveyed into a coal seam drilled hole, the carbon dioxide phase change coal seam fracturing device can be rotated or directly pushed into the drilled hole through a drilling machine, and the situation that the cable is broken during external connecting is avoided; no other special equipment is needed, the depth of the part conveyed in the drilled hole is not limited, and high work efficiency and reliability are achieved; and a screw structure is adopted and directly screwed in a coal body, drilling links are reduced, the screw structure is beneficial to powder discharge and meanwhile is closely embedded with the coal body, gas acting force is improved, the fly stop problem is thoroughly solved, and high reliability is achieved.
