description The invention provides a reusable static rock breaking efficient heat conduction hole sealing device, and belongs to the technical field of coal mines. Comprising a heat conduction pipe body, the outer side of the heat conduction pipe body is connected with a hexagon bolt, the upper end of the hexagon bolt is connected with a metal round blocking piece, and the lower end of the hexagon bolt is connected with a metal round nut; the outer side of the metal round nut is connected with a rubber cylindrical sleeve, anti-skid protrusions are arranged on the outer surface of the rubber cylindrical sleeve, and the heat conduction pipe body comprises a heated section and a heat dissipation section. The heat conduction pipe body fully releases huge heat generated in the reaction process of a static blasting expanding agent in the hole; the metal circular separation blade has the effects of secondary drilling hole plugging and clamping supporting; anti-skid bulges are arranged on the outer surface of the rubber cylindri
