The invention discloses a gas spacer puncturing device. A gas spacer treatment device comprises a puncturing rod and a puncturing head; a first end of the puncturing head is mounted at the head end of the puncturing rod; a second end of the puncturing head is a puncturing tip end; a gas guide groove is formed in the outer surface of the puncturing head; the gas guide groove extends from the first end of the puncturing head to the second end of the puncturing head; multiple guide plates are mounted on the side surface of the puncturing rod, and are uniformly distributed in the peripheral direction of the puncturing rod; and an electrostatic lead is connected to the puncturing rod. The gas spacer puncturing device enables a gas spacer clamped in a blast hole to effectively shrink to prevent generation of friction static electricity or sparks, so that damage of the hole wall or blasting of the device is prevented, the blasting effect of the blast hole is guaranteed, and the drilling cost is reduced.
