The invention discloses a coal gangue deep heat removing system based on a heat pipe heat exchange technology. The whole system includes heat pipes, a circulating water pump, and heat exchange equipment, evaporation sections of the heat pipes are buried in coal gangue, coal water slurry is utilized as a filler, and rust-proof treatment is performed on the outer walls of the heat pipes. The evaporation sections absorb heat of the coal gangue, mediums in the pipes changes from a liquid state to a gaseous state and rise into condensation sections in the pipes, circulating water is introduced intothe condensation sections of the heat pipes, the circulating water absorbs the heat of the condensation sections to carry away the heat, the heat is dissipated by the heat exchange equipment, and theheat of the condensation sections is continued to absorb. Compared with technologies such as deep grouting and fire extinguishing, local excavation cooling and deep injection of inert gases methods,the coal gangue deep heat r
